And by "fired first", Israel didn't just fire first conventionally, but in terms of nuclear weapons, firing seven into Russia with one hitting Moscow and killing the insane Russian President and the other six being shot down. But anyways, what did you make of how many Polish soldiers decided to fix bayonets and make one last suicidal charge instead of surrender in Clash of the Worlds when things were doomed for the United Nations (desperate measures after India and the UAR surrendered and fear of countries jumping ship like those two led to the A4 centralizing high command and trying to integrate national militaries into a single United Nations Armed Forces)? How much was it driven by the crimes the Nazis had done to the Poles?
Well, India, UAR and Japan. Japan being much earlier than the other two, and actually outright defected instead of surrendering, actually contributing troops to the Coalition during the war similar to the German statelets and AANW China including the invasion of AANW Australia and the USA West Coast.
You know, I always wondered why they chose to name it Earth Solidarity Pact instead of the UN, but then I realized it all made sense given the name of united military of the AANW nations and all the war crimes and atrocities committed by the United Nations Armed Force during the war probably would leave the name a bad taste to everyone mouth, especially when trying to use it as a name for an organization based on safekeeping peace on the three worlds.
As for the Polish, I am quite positive that many of the Polish soldier during the war truly believed that they had no choice but to fight till the death and many of which influenced by the memories of the Nazis of their world. Marek Stepien battalion during the last stand at Washington however probably all realized the truth of what they are doing and how they are becoming the monster they sworn to fight, yet instead of surrendering, they chose to fight in resigned yet firm resolves. After all, almost all of their loved ones and friends are dead or missing by then, and what they swore to protect is lost when Poland fell and United Nations defeated, their actions would be held accounted by their enemies who would dictate the fate of their homeland and all they loved and are very unlikely to be merciful after the deaths and pains the United Nations Armed Forces have caused during the war.
