The USA needs to get out of the business of solving the world’s problems. I don’t mean to be heartless, but we have a boatload of problems to solve right here — and prejudice against Christians is one of them. I’m real happy if Israel takes out Iran’s nuclear capability and possibly causes regime change. But Trump? Confront Iran? Over their internal issues with Christianity? It’s a bad idea.
Wrong: confronting Iran as well as China, etc. over their punishment of real Christians is wholly consistent with opposing Iran as a military threat against the US, which is part of its larger war against vibrant evangelical Christianity, which the Western Left also wants to extinguish. The fact of Islamic persecution of Christians by Iran makes Trump's opposition to militant Islam more justifiable and stronger, if not being the only reason.
While getting your own house in order does take priority, yet insofar as that is done, it means dealing with both evils within as well as without, and supporting those who are likewise threatened by them. And it is right and consistent with MAGA, which must mean great in the eyes of God.
