I don't know if his attacks on NATO are truly driven to make them more responsible in shouldering its cost or that they are actually a sinister intent to destroy it. His appeal is far too confrontational and doesn't take in the realities of the economics of that have plagued some of its members.

I don't know why he didn't appeal to its members in saying that we are faced with a renewed threat by Russian that has used military force to take over the Crimea and is attempting to do the same in the Ukraine and that it is imperative that we remain united and take positive steps to increase our defense. This will include substantial contributions by every member to met the threat with determined resistance.
