In my personal rather unimportant opinion, U.S. national influence and power will diminish
over the next decade which, in sum, is a benefit to world peace and progress.

Let's hope so! The USA has been allowed to have its own way for far too long. Fictitious WMD in Iraq; the excuse to cause mayhem in the Middle East, (in the name of 'War on Terror'), as a follow-up to their own orchestrated disaster known as 9/11. The list goes on and on, but I really can't be bothered to cite it all. Even their refusal to show the world the dead body of Osama Bin Laden, after he was allegedly killed, stinks!
The American government is the most corrupt in the world and yet everything is 'hidden in plain sight'. There is no doubt in my mind that this whole pathetic charade would continue with Killary in the 'big chair', yet there is a tiny, miniscule, glimmer of hope that Trump will at least TRY to ensure that it doesn't continue.

More and more people need to wake up!
