You forgot that also Obama wanted to do this. In the last 20 years every US President wanted to do this.
But he didn't.
Sometimes when you are rational, sane person, you realize some of you wishes can't be realized. I'm sure a lot of politicians do not proceed with their campaign promises because when they get in charge and realize there are other consequences, they do not go ahead. Yeah it pisses off some people but only dictators and insane leaders never change their minds.
