Talmann. Did you hear about the Madrid and London bombings? Why don't you go and tell the families of the victims that no-one is attacking Europe because it doesn't matter?
At New History Lovers, the USSR could have destroyed Nazi Germany single handedly, of this I am positive. The bombing of Germany by the Allies helped, with vast resources being withdrawn to defend Germany, as did the Second Front in Northern France. However, when Stalin said that he would turn the USSR into a 'single war camp', it wasn't rhetoric. Once it got going by late 1943 Soviet production far outstripped that of Germany. Your analysis of counterfactual outcomes of World War Two seems to be entirely ignorant of any understanding of Russia in that conflict.
American intervention in WWII helped secure the victory which eventually was. If America did not intervene, there would have been another kind of victory. A victory which would not suit us Westerners, but a victory over Nazi Germany nonetheless.
The USMC wannabe in this thread earlier stated that Americans 'live by principles, fight for principles and die by principles'. First of all, this laughably seems to imply that elsewhere in the world, people don't fight for causes, they just fight for the hell of it. Second, it takes a very myopic view of American foreign policy. Shall we look at the War of 1812, in which America allied herself with a dictatorship to attack a democracy? Or shall we look at the 1970s and 1980s, when America funded insurgents and even sent her own agents to undermine democratically elected socialist governments in Latin America?
I am not saying the US is worse than every other country. What I am saying is that it's the same, no better, no worse. The US acts for its own interests, just like every other country. It's called realism, and it's the way the world works. You can try to justify it anyway you like, every country does. For the last couple of hundred years the method of justification in the West has been 'liberal democracy' and, more recently, 'humanitarianism'. To truly believe all this, though, takes a special kind of blinkering that no human being should be capable of. Sadly, not everyone engages their intellect as much as they should.
