Quote: I think your wording is a bit off. Trump did not surrender to Nancy Pelosi. He granted a 3 week reprieve so the federal workers can be paid and to try to get everyone back to the table to negotiate a deal. He said if a deal is not reached in 3 weeks that he would either shut down the government again or declare an emergency and go around congress for the wall. I am glad the workers can get paid but this is not over by any means.
The wall is over. Trump's position was that the government would be shut down until he got money for the wall. Pelosi's position is reopening the government without funding for the wall. Pelosi got her way. Trump surrendered. If Trump didn't surrender, his base wouldn't be howling. Hannity's listeners who called in today were very upset with Trump. The Republican Congress doesn't have the stomach for another shutdown, so it's not happening. Declaring an emergency for the wall will get legally overturned in all likelihood (even if it goes to the Supreme Court), and if it doesn't, then it will set a precedent for a Democratic president to have tremendous power to declare an emergency over climate change, a much more real emergency. Republicans realize that and so have warned Trump against going this route.
That you admire doing "a lot of harm to immigrants" is pretty scary. That you hate people enough to wish them harm? What is that?
It would also probably have legal challenges. It is possible, particularly if he used the army, that it could get held up for some time. Then could just be taken back anyway. It would be pointless. Other than PR.
Particularly when he was undersold by the intelligence community recently. The PR would only be to get love from the base. Which is all Trump does.
