It's funny what navel gazers with computers can come up with. The US is an easy and obvious target for the leftards. The problem is that most folks can't differentiate between left and right, and it doesn't seem to be taught in many poli sci courses. Left and right got muddled by Stalin, who distanced his regime from Hitler's by labelling the latter "Right". Goebbels only verbalized what every despost already knows that if tell a lie often enough and it becomes the truth. In fact, politically, left is total control and right is no control, (anarchy). The "religious right" is a misplacement by the left, just as there is no such thing as a right wing theocracy. A controlling government driven by a religious ideology is no different from a left wing government driven by a Marxist ideology. Labelling the former "right wing" serves the Marxists well as it gives the appearance of being left with only two choices. The US has drifted left ever since independance and is only a shell of the republic it could have been. Though the US has many issues, all societies move leftward as citizens make more and more demands on their governments, gimme gimme.
As for blaming the US for the arms race, Deuschland started it, twice. The US just had the good fortune to employ German scientists who had defected. The US had no political backing or stomach for war until the attack Pearl Harbour. Of course no one blames the Soviets for the arms race that continued after the war either, глупые Американцы.
Has the US engaged in wars they had no business in, sure, but they are not alone, again just an easy target for critics.
Corporate greed is not an American invention either, and if the US was the cause of the "global meltdown", why is it that Europe is in worse shape? The first dacade of post Soviet Russia is a testament to Capitalism without the rule of law; although the players are different, (the crooks use pens more often than guns, and wear ties instead of maskes, but the companies and employees are still pillaged), the US is not alone in Capitalism run amok.
Achieving peace is realtively simple; China has it, most of the Middle East would have it too if they weren't so concerned with wiping the floor with Israel. Peace only requires that you surrender to, and be subservient to your oppressor, you only need to give up your freedom. Liberty, on the other hand, requires work and vigilance, which is why the left opts for the easy route.
