Ignoring a country and regime that's murdered hundreds if not thousands of Americans over the years and was working to develop a weapon that could kill millions seems like an insanely stupid thing to do. Obama and Biden did nothing but tried to assure us we would be just fine.
That shit doesn't fly anymore. Trump has changed the game ... and for the better.
I think the assassination attempts and his second Presidential victory changed him. He considers himself saved for a reason. And he's determined to do whatever it takes to make the U.S. a safer place and screw those who disagree with him.
