This is quite funny but hey heres my 2ps worth
a world without America......................ok the video states near the start that the Red Army liberated Paris instead of the US, but wait one moment, back up, if old Hitler hadnt had to worry about the US attacking from the west who's to say he would have lost the fight against Russia, remember a primary contribution to Germanys downfall was trying to wage a war on 2 fronts, the UK without the states was more of a hinderence then a serious threat, no B17 flying fortresses dropping bombs on his industry all day, so inclusion isnt possible that a world without America would mean Hitler may have conqured all, now while this may seem bad, lets look at the fallout, If Germany reigned dominence over the globe its possible the middle east wouldnt be what it is to day, back then in the 40's with Germany bellowing on about the supreme race an all that shite its douptful the middle east would have been left to grow into what it has become to day, also about all these inventions America has bought, Germany during the war did a fair bit of devoloping of its own, like the jet engine and the early stages of Atomic weapons like devoloping heavy water for the hydrogen, so its safe to say in this wee mans opinion without America and what they have given the world, Germany would more than likely have done it them selves and the its douptful that the middle east would be as pissed at the west as they are now due to an almost complete lack of even exsisting.
