I think the problem is that you dont realize how little the US cares...
The sooner you realize and understand that the US is very purposefully pulling back from its relationships, the sooner you can stop crying in your cheerios and stamping your feet like a child..
the only question is how much pull back is the appropriate amount? there are very far/hard right isolationists (your boy Joe Kent that you seem to love and appreciate is one of them by the way... which makes you a bit of a duplistic hypocrite I believe).. and there are centrists that do believe the rest of the world needed to be put in check, but to a lessor degree than the Kents, Vances, Hawleys, etc..
The other thing you fail to realize is.. if the global economy takes a dive.. YOU will most likely hurt much more than the US..
The US economy is simply larger and able to take a beating much more readily than most of the rest of the world..
Everyone sucks during a global recession..
But generally speaking the US sucks less than everyone else..
The US felt the last recession from 2008-2010...
Europe got a double dip and re-entered recession in 2011..
The US staggered around 6.7% unemployment for most of the recession while Europe hung around closer to the 12% mark..
