Being completely honest, I just think of all these conflicts and crisis' as continually kicking the can down the road. We used to kick a** and not care about the world reaction. Think about it. For 20+ years we can't even secure the southern border of our country. We can't figure out health care.
In just five years we went from depression and having the 19th ranked Army in the world to defacto global superpower.
We used to kick butt. What happened? Seriously? Regulations? Rules? Political correctness? Globalization?
Health care and the southern border have failed because of internal conflicts. We're designed to be a democracy that exists for the benefit of the public. But we're actually an oligarchy run for the benefit of the wealthy. (And from the perspective of the 1%, everything in America is going very, very right. Espeically for the sociopaths.)
We were supreme after WWII because every other advanced nation on earth had been wrecked.
When do you think was this time we used to kick ass and not care what the world thought? Because the idea that we did so anytime after WWII is a product of jingoistic propaganda.
Korea? Vietnam? Somalia? Putting together giant coalitions against third tier nations like Iraq and Yugoslavia, and still not accomplishing all that much? Trouncing Panama and Grenada?
What I think it really happening with 'kicking the can down the road' is that our own propaganda about how awesome we are is starting to have it's wheels come off when faced with the consequences of unfettered greed by the 1%. (Once the Cold War was over, there was no more incentive to make things better here than over there. They've descended to trying to frighten us with scary brown people who don't speak English instead, and it's still not quite working right.)
