Well my friend muzungu, if you can predict exactly what Mr. Trump will do, on any subject, you sir are light years ahead of the rest of us.
To speak of the last 20 years and the warmongering committed by the USA please make an exception to the last 8. President Obama made it a point to NOT send masses of Americas best into combat. He did after much deliberation and on the advice of his loser military advisors escalate in Afghanistan to little avail. "just 3 more years and we can turn this country around", these are the same officers whom wanted just a few more hundred thousand to turn Vietnam "around". They made it a point to disregard the premises in their own anti guerilla warfare publication.
President Obama forced a change in Iraqi leadership and now an actual coalition of the groups we and others forced into the boundaries are involved in taking back the last major city in "Iraq", without a major bloodbath of our finest citizens. 
Will Mr. Trump be as thoughtful and careful? bruce
