The premise of this map is that November 1942 Germany and its occupied territories, as well as May 10, 2017 Israel/Palestine, are ISOTed to a Virgin Earth. This is the world one hundred years later. For the record, I want to say that I don't agree with the popular Austrian opinion of the world expressed below.
The Initial Israeli Response
*It took the Israeli government roughly an hour to conclude that its neighbors were gone. Syria, Jordan, Egypt, all disappeared and replaced with wilderness.
*It took another half hour to conclude decisively that the rest of the modern world was gone as well, besides German radio signals, and it didn't take very long at all to figure out that this was not Merkel's Germany.
*Tel Aviv had a good panic when they realized that the radio signals were coming from a Third Reich at their strongest, and on May 12, 2017, by the Israeli calendar, the first battle between Israeli and German forces occurred over Crete.
*It was a crushing defeat for the Germans, even with the Israeli confusion. The pilots had been briefed on the best targets, taken from historical archives, and the German presence on the island was essentially eradicated over the course of four hours.
*But the Israeli government realized that continuing this practice over the entirety of occupied Europe would be useless. Not only did the Germans have a larger military than theirs, even if it was less advanced, but they controlled half a continent, and the Israelis would run out of resources soon enough, to say nothing of food.
*Israel's navy, civilian and military alike, was repurposed for fishing, and for decades, that section of the Mediterranean would suffer the consequences of that overfishing.
*The Palestinians responded poorly to Israeli attempts to restore order to the rioting territories, and the fighting between the two escalated, to the point where the Israeli government was more focused on their own territory than the Germans.
*This wounded up being irrelevant. Tel Aviv's fears of a German attack on Israel proper would prove unfounded. Berlin was terribly confused over the ordeal, seeing wilderness in the place of their eastern front.
*In the portion of the front contiguous with the rest of the Reich proper, organized 'legitimate' Soviet resistance was defeated fairly quickly, without supplies to support them. The Murmansk occupation zone, however, cut off from Germany proper, and with the rest of the Reich disorganized, found its hold on its territories slipping, and resistance from the Russians there proved unbearable. The heroic retreats from German-Finnish soldiers would prove a popular subject in German films in the future.
*By week two, Germany had largely secured control of its contiguous eastern territories, the military machine working well enough in that regard, but found their own population panicked and confused at the whole ordeal. This would only get worse for them.
*By week three, Israel had quelled the riots in Palestine, and its attention turned to Germany. Netanyahu made a tough choice, and one that's controversial in hindsight, although perhaps not as much as later Israeli decisions. He ordered forty nuclear missiles launched at German cities and military bases alike, and continued conventional strikes on lesser military targets. Mossad made short work of individuals of import who weren't killed in the nuclear strikes.
*For around twenty years or so, there was a genuine fear in Israeli circles that Hitler was still alive. The assumption was that he was killed in the vaporization of Berlin, but, of course, there was no proof of that. A deep fear in Israeli culture was that Hitler would return and reunite the Germans against the Jewish people.
*In the months after the initial nuclear strikes, Israel would continue by striking down organized Nazi military movements, what was left of them anyway.
The Modern Day (2117 or 2042 depending on your political leanings)
*Israel's not the unquestioned hyperpower it was in the initial chaos post-ISOT. Its technology has proliferated, and France, Ukraine, and Poland all have nuclear weapons of their own. The Internet has been restored, although it has not yet fully spread to some portions of former Germany. Tech is roughly 2020s in the more developed parts of the world.
*Israel's also a fair bit different from what it was one hundred years ago. It offered unlimited sanctuary to all Holocaust victims, Jewish or not, helicopter fleets flying to and fro Dachau and Auschwitz and the like, ferrying them to Crete (the only European territory ever officially occupied by Israel) or Israel proper.
*The surplus of undereducated (by modern standards) citizens would create a new class of sorts, farmers, fishers, and other laborers, who were the brunt of the colonists who would settle the virgin earths. Like on most ISOT worlds, farming was the reason colonization of the wilderness was begun.
*Palestine has regained its independence after the tenuous period post-ISOT, but it's essentially two states nowadays, Gaza and East Palestine (the name is a relic). Tensions between Arabs and Jews have largely faded, as most of the radicals and the like have fled to New Palestine (more on that later). Both states are submissive to Tel Aviv, and they share an open border arrangement, as well as a common military.
*Crete has a similar relationship with Israel. While it initially rejoined Greece proper after the local resistance, in tandem with Israeli intelligence, arms and air support, forced out the occupiers, Crete severed itself from the poorer mainland after the Greek government became more and more authoritarian and demanding. While that regime soon disappeared after Israeli-Ukrainian support dried up, Crete is perfectly comfortable with its independence. Like Gaza and East Palestine, it has a common border and military with Israel proper.
*Israel still has control over the Gibraltar and Bosphorus Straits, a bit of foresight on Tel Aviv's part. Colonization of the world past Europe, the Middle East and Maghreb has not yet begun in earnest, but when it does, Tel Aviv hopes to make a killing on shipping fees.
*The second most powerful state on Earth is France. Paris declared independence from Germany after the initial Israeli strikes, and was lucky enough to evade most of the nastiness and warlordism that ensued in the following years.
*France hasn't had much interest in colonizing, but even their lackadaisical attitude towards settlement has resulted in them having one of the most rapid territorial growths in Europe.
*France was never especially interested in Israel's anti-German alliance, and created its own bloc out of Holland, Belgium, Luxembourg (a historical relic France contemplates annexing occasionally), and Rhine.
*The French state, like most independent European states, is a lot more German than you'd think, the refugee population meaning that twelve percent of Frenchmen speak German as a first language.
*A small Catholic state has been built in the Rome area, and provides a neutral space for the powers of the world to gather and meet.
*In the majority German areas of the world, Austria is the predominant power. Vienna did not escape the nuclear wrath, but the Linz area proved to be a source of stability in the region, and that was more than enough to rebuild from. Austria survived the initial period by portraying itself as a moderate, repentant German state, and Israel gave it reluctant support.
*This didn't quite last to the modern day. While Austria nowadays is a flawed democracy (think Russia), all major politicians agree that Israel's initial response to Germany was overkill and bigoted, that the Holocaust didn't occur quite as Israeli records state, that the German people were not to blame for Hitler's actions, and that the Germans and Palestinians are equally victims of the Israeli desire to rule the world. Dogwhistle and blatant anti-Semitism is common, especially in the more developed parts of the world. Those that are less developed have largely forgotten about Israel, and are just trying to get to a modern-day standard of living.
*Bavaria and Hanover are poor agrarian states struggling to catch up with the world. Despite Austria's wishes, neither really wish to join them, being focused on repairing their own infrastructure, and dealing with the brain drain issue. Nazist parties are popular here, but not dominant. Politics is rather violent in both countries, with the moderate-capitalist party in a tripolar conflict with fascist and socialist oppositions.
*New Palestine is a project by the more independent-minded Palestinians to create their own state, and while Tel Aviv was initially concerned that it would prove a hotbed of jihadism, it's more become a hotbed of angry farmers who spend more time fighting each other in land disputes. Austria supports them, mostly to spite Israel. They're really not as bad as you'd think, besides, you know, the anti-Semitism.
*Prussia is the second-most powerful Nazi successor state, and the richer one to boot. Much more moderate and reasonable, Prussia keeps its head down, and most of the world forgets it exists. Unfortunately, it's growing friendlier and friendlier with Linz, which concerns Kiev, Warsaw and Tel Aviv.
*Norway is happily independent, having escaped most of the consequences of the post-nuke chaos, but has struggled to absorb its German population, and the right-wing authoritarian party is presently dominant. Past administrations 'politely' 'asked' most Jews to leave for Israel anyway, so at least there aren't many worries in that regard. Currently competing for territory with Prussia in former Sweden.
*Czechia is steadily growing, but there are concerns that Poland might eventually cut them off. Prague is looking into purchasing territory from Warsaw, but many worry it might be too much cost for too little gain.
*Silesia is a historical relic, a warlord state that civilized and then never went away.
*Poland is a powerful state, and has its own power bloc in Central-Eastern Europe. Czechia, Silesia, Lithuania, Estonia, and Latvia all answer to her bidding, and she's claimed most of the Balkans, having a reluctant agreement with Austria, Ukraine, Greece, and Newhopeland (a translation of a German name. We'll get to them later.).
*Poland is more concerned with the resurgent Soviet Union, which, after decades of petty warlordism and poor infrastructure, is finally becoming a power in its own right, and starting to make aggressive moves in former Finland, where both Estonia and Poland have territory.
*The Soviet Union is the final result of violent reprisals against Germans and rival warlords in former Russian territory, a despotic communist state that none of the Eastern Association (Israel-Ukraine-Poland) are willing to associate with. They're growing at a pace which worries most other governments.
*Greece has largely recovered from its original strongman-authoritarian days, and has contented themselves with being a poor agrarian state under Ukrainian influence.
*Newhopeland was a project by German refugees in what we would call Albania who were unsatisfied with their choices, and has become a fairly successful feudal state. The militias who kept order in the initial days have given way to a bizarre system of modern-day lords and serfs, one that the rest of the world watches with bemusement. This national experiment will likely be subsumed by Austria someday in the next few decades.
*Finally, Ukraine. The third most powerful state in the world after Israel and France. The initial collaborationist regime was killed off in a brief but bloody civil war, and the country has since recovered with Israeli monetary support. Tel Aviv's most loyal ally that isn't a client.
