(1) The way one thinks about things directly affects one's actions.
(2) America has the power to (and does) take powerful action.
To quote the superhero, with great power comes great responsibility. The problem is being uninformed about other worldviews WHILE taking action that directly influences others, sometimes to an incredible degree.
Like Geoff said, America as one entity is grossly divided from the world as one whole, whereas most countries have a greater international focus. I don't think the pressure is meant to be applied to any one American, but rather to awaken you guys to the fact that there's a reason Americans who haven't taken the self-initiative to break out can be identified as such. A lack of integration and interaction with others becomes readily apparent. Which is cool, it's your lives, and I myself am not bilingual or well-versed in a lot of international politics, but I at least make an effort to grow because I see that there's things I can't see yet. The OP of this thread is some TCK American, and he "sees" a lot of things that other Americans can't see unless they take the initiative to go looking.
