No doubt Europe has problems. Just take a look at Europe from a historic view. The dark ages, black plague, Hitler, rise and fall of Greek and Roman empires, Viking envasions, steeling from and killing Aztexs, Mayans etc. Yet they are still there and often critical of others. Something tells me that they really do not care about anyone else.
That's probably why J. Dimon stated that the USA has a royal flush AKA the worlds best military.
How would you value the USA military? Priceless? What debt? Make me pay!
