I've got great news for you, the enemy of your enemy can still be your enemy. Newsom doesn't even really disagree with what Trump is doing, he only disagrees with how.
Gruesome newsom is currently waging a war on the homeless. Not homelessness, the homeless themselves. He's cruel and comes into the defence of capital full swing.
I don't want any troops dispatched here (the national guard is theoretically fine if a lot was different), but the marines are probably best of the branches. They're the advance troops with minimal additional stuff. The army is the big guns, when they arrive its no longer skirmish or mild occupation, its gonna be a while and its full on martial law.
There shouldn't be soldiers oppressing the people who live here at all, it violates the Constitution. But for what it's worth the Marines are ground troops.
