My opinion is President Trump knows damn good and well what this is all about. During the meetings I bet in no uncertain terms that President Trump is telling them in a nice way that none of these arms better wind up in the hands of the terrorist.
Also IMHO we need everyone we can get to annihilate ISIS and rein in Iran. Again IMHO Iran is the biggest threat in that area and North Korea their ally is another big threat. It is a global effort.
I thought the President of Columbia practically said as much. In today's presse, the Saud said they'd respect the results of the Iranian election and their right to self-determination. What would not be tolerated is destabilization of other countries and supporting ISIS.
