The easiest way to increase war fighting skills and effectiveness is to get rid of the left wing social experiments put in by Obama and maintained by Mattis. Clean house of Obama Generals who are insubordinate and dragging their feet, insist on instant obeying orders and ensure the folks at the Pentagon understand Donald Trump is the Commander in Chief, not the courts, not the Congress, not the media.
Being a “business guy” sounds good to me. That is, pragmatic but principled. The US press and former government figures have, for variously mostly left wing ideological reasons, been trying to sell Islamist radicals or leftists as the “freedom fighters” that we should support. They’re not.
What we really need to support are those governments that guarantee support for free trade, freedom of movement for their people (many dictatorships do not let people move to more productive areas), and the basic rights of man.
But it’s all got to be related to what benefits the US, and one of the reasons we’ve lost clout is that we were just doing things that only benefitted the UN and had nothing to do with the US.
