Two interesting quotes, "All 28 NATO allies are individual members of the 68-nation anti-IS coalition. Some, notably France and Germany, have feared that NATO officially joining it might upset decision-making within the coalition or alienate Middle East countries taking part." But in remarks that humiliated other leaders, Trump said that “NATO members must finally contribute their fair share and meet their financial obligations.” 

Yes, we don't want to "upset decision making", and the last thing we need is our President making "humiliating" remarks to other leaders. At what point is the PC nonsense going to end? Apparently Trump didn't read the last President's memo; the biggest threat to the world is climate change, not IS (actually, I believe it was "ISIL", but only a scholar would use such a term). Of course, all the foreign leaders are protected by layers of armed guards. Maybe their opinions would change had one of their children been murdered by a Radical Islamic terrorist.
