Well, I sometimes wonder whether Europe and the UK looked to America as a 'great hope' for the future back in the 70's, they were in space, pushing the word of 'freedom', far from perfectly, but then Europes' History is just as patchy.
I guess I always felt a bit 'let down' by recent American actions, they were supposed to be the country that taught the world that life was more important than control, that learning and personal individuality to believe what you choose so long as you hurt no-one were rights that were to be defended at all levels. For a long time after WWII, Americans had a lot more Freedom than their European counterparts, despite what many Americans believe, the shadow of Facism still loomed over us, creating suspicion and distrust.
I feel dissapointed because, to my mind, America has lowered itself to the same level as the petty Dictators that could barely shake a stick at it, they resorted to violence, intimidation, and leeching from countries they invade. Whilst this has always been going on at a low level with every country, of late in the US it has become a brazen, unashamed exploitation with the flimsiest of excuses, and a terrible cost on both sides. There used to be a belief in China that outside the borders were 'ghosts' and that anyone who wasn't born and raised in China was not human. I certainly see shades of that thinking rising in certain parts of America.
That is why my opinion of America has dropped, I still think it has the potential to lead the world forward, but right now, like a cancer, it has started to eat itself to survive. Look at your national debt for proof. I am worried because if America carries on without massive changes in Foreign and Domestic policies, it WILL collapse, and will probably take 1/3 of the planet's economics with it, what happens after that is anyones guess but it will certainly be Anarchial for a while.
