tyran, homeworo assignment: watch 30 minutes of fox/cnn and then the same news segment from BBC news, RT news and Euronews.
Reflect on the difference in the quality of the propoganda being produced, the bias in respect of world news events, and how each countires national priorities are reflected in the piece.
Oh, nobody is saying the US is 'evil' and trying to destabilise the world. The want control and power, destabilisation (as caused in Afghanistan and Iraq, and assisted in Libya or perhaps Syria) is merely a means to an end. Having a 'democratic and free' neighbour is less important than having an ally; democratic Egypt may not support the US (even if individual egyptians love America, they can still hate the American government. And equally the Egyptian government can still hate US cultural influences and thus be motivated to undermine them.
Egypt is a great example because it was a US ally, and the US wanted to sit back and see what was going to happen, better still it seems the militrary was not going to interfere and pick either side while it could avoid doing so, because the egyptian militrary was largely loved by the people and they acted in their own interest gaining much power in the process)
America is not evil either - they're doing what every other imperial power has ever done. It could be said to be human nature. Or an emergent feature of human social/power structures.
But if you ignore the propoganda and bias, and then simply look at the behaviour; fundamentally it differs very little from any other empire.
