“In difficult ground, press on; In encircled ground, devise stratagems; In death ground, fight.” - Sun Tzu:

It is that last one, Death Ground that President Trump has proved the master in. Death ground is where retreat is not possible and you either triumph or die. President Trump has been the master of putting the RINOs in congress onto the political equivalent of death ground. He provokes the enemy so that there is no chance of negotiation. He ensures that defeat will end the careers of the congress critters in question. Share in the president's victory or be uterly destroyed along with him, take your pick.
