I think it's quite amusing to see people theorising on the B29s winning the war with Russia

. Any army needs infantry to win and hold territory. On the ground Russian tanks would be shoving the remains of Allied would-be-assailants into the Mediterranian before the B29s from the first air assault would return to their bases.
By early '45 nothing Allies had was even comparable to latest Russian tanks arriving to the front in droves - IS-2s (IS-3s and T44s just missed the action but were manufactured and shipped to frontline tank divisions). Majority of Soviet infantry carried automatic weapons. Il-2s/10s were never actually matched in their day as an air-to-ground attack aircraft... And the army that had just defeated Hitler's Germany had the best combat experience and highets possible morale.
America reigned supreme in the Pacific/sea battles and in startegic bombing but on the ground... Let's just say you guys weren't the best, OK?

Exhaused industry? Sure, in "mainland industrial Russia" it was actually non-existent as Germans destroyed anything they couldn't take with them. It was different story altogether in, say, Novosobirsk - a town (wasn't obviously as big in those days but now ~1.5 million people) in the middle of Western Siberia where all factories were working in full swing building planes, tanks etc...
Allies planes using bases in China? You do remember who is in power in China, don't you? At the time Mao Tse Dung was the best friend with Russians - they brought him to power after all.
Nuke the bastards? Hmmm... How many A-bombs did US have at the time?
Allies landing in Siberia? Hmmm again... And then what? The Soviet Union used to occupy 1/6 (!) of all landmass on this planet. You land in Vladivostok and it's a 6,000 miles to Moscow - through mud, wilderness, forests...
Guys, no disrespect, but you have no idea what you're talking about when you say "we ran a wargame and..."
I've been watching all the experts on Russian affairs available in this country for the last 10 years - and they just make me laugh with their "assessments".
On the other hand, it's great to see some people whose outlook on history does not seem to have heavy anti-communist bias - <S>!
p.s. I was also wondering how your
democratic government would explain to the voters the unprovoked attack on an country you fought together against Nazis just a few days ago with hunderds of thousands of casualties to boot arriving in a very short order?
p.p.s. I bet you anything that if you run an "wargame" with an American army, Navy and the Airforce attacking with all they've got a small country in, say, Indochina...
