No, I disagree wholeheartedly, with everything you just said. This "civilization" you speak of, is basically the US, and solely the US. Other countries are affected sure, but the States is taking the biggest hit of all of them, and yes it will significantly affect US trade, foreign policy, and the ability to produce and retain more sheep.
Your second paragraph does not make any sense. From your "Grand Perspective stand point" (what the hell is that anyways, like god's view from high up in the clouds?) this affects Middle Eastern relations with the UNITED STATES. The US does not represent the world - as much as it would like to, and strives to do - and what negatively affects the US does not necessarily affect the common good or the rest of the world, though your concern is greatly appreciated.
I would also like to refute your argument that all your public servants are acting with the best interest of the country in mind. In no way, is this true. Yes there are some people that do act to for the benefit of the country and you, the citizen, [sometimes] but a great number of, if not most, of your officials are corrupt in some way. By nature, their interest is to be reelected (even for "good people, since to do that good, they need to be in office) and they will do whatever needed to accomplish that goal. In fact, they don't always benefit when the country is "doing well" either. I could explain but I feel like I'd need to write an essay to do that.
Of course it has an impact on your American image. Whether that image does justice to what is actually going on behind your back, I'll leave you to decide.
Lastly, your economy is already so far down the shitter this probably won't have any significant impact on it, other than the fact that some people may be pissed at you and refuse to trade with you. Maybe you shouldn't have been doing whatever that pissed them off in the first place.
