War.
They hate Trump because he's against their constant and never-ending pogrom of mass murder and war. There are too many war pigs eating at the trough... lining their pockets with the earnings of the productive middle-class... before aiming their weapons directly at the middle-class they bled dry.
Jacob G. Hornberger explained the situation this way, just a few years ago.
Why They Hate Trump So Deeply
Would you like to know the real reason for the deep, unfathomable, uncontrollable hatred and rage that these people have for Donald Trump?
I’ll tell you what it is.
It is acceptable practice for any politician and bureaucrat to criticize things that happen within the Washington, D.C., sandbox in which these people play. But woe to the politician or bureaucrat who challenges the sandbox itself. He is toast.
No president since John Kennedy has dared to do that. Kennedy did it, especially in his famous Peace Speech at American University five months before he was assassinated. He said that the Cold War was a crock and that he was calling an end to it, which, needless to say, constituted a grave threat to the sandbox in which the national-security establishment had been playing and hoped to continue playing for the indefinite future.
Trump challenges the DC status quo.
