Having read reviews and comments on Man with the Iron Heart, saying that it's Iraq 1945, I got to thinking about how the Allies would handle a serious and effective resistance after Germany fell. (I haven't read it, and as yet, don't plan to. I'm contemplating this as in independant thread, unconnected with events from the book)
My first thought was the end game, if the Allies should, somehow, decide to leave. I think they would implementation a strict de-industrialization of the country, dependant oninternational relief organizations simply to eat. And the de-industrialization would be enforced by B-29's. If they build a factory, we blow it up from the air. If they build it too deep for us to bomb it, or too well hidden to bomb it with precision, we use an atomic bomb. Heavy forces, while no longer occupying the place, sweep through suspect areas. A factory can't evade an armored division. Informants are bought, and later evacuated to a safer location. Radios are forbidden...and destroyed my bomb or rocket if they transmit. I think that, in the aftermath of a dreadful war, with a continuing effective resistance, the Allies wouold not leave any sort of potential for industry. It would make Versailles look like a kind, gentle treaty.
I think, though, that the Allies could probably deal with a resistance. People that get fed, and no longer see bombs falling on them, might want to keep it that way. And the die hards that plant bombs in their towns, and bring more war upon them...they might be sold out more often than they expect to be.
Those captured in arms against the Allies, when out of uniform...shot. For that matter, the war is legally over, so shooting Allied troops is murder, plain and simple, according to the laws of war, even if they were in uniform.
And, some local officials might be co-opted into helping the allies. Even some SS, when looking at a firing squad if they don't talk, might squeal.
And, in 1945, the USA was in a war mindset...and I don't think they would want the enemy coming back. It's not like today, where the Iraq war is debated endlessly, and the reason for going in is debated...there was almost no doubt, in World War II, that we needed to be there.
And the Russian zone...well, I think they'd be as quick to murder hostages as Turtledove's USA after Featherston's boys surrendered.
How would the USA, France, Britain, and the USSR deal with the resistance? And how much of one could German irregulars put up?
