There are rules against much of what trump is doing.
The rules you and I exist under are strictly policed and enforced. That is what most people think of when they think of rules. Liberals think of Big Mommy. The problem for liberals is that Big Mommy is not coming to save us. In reality our rules are enforced by a monopoly of violence done to us by the state, no such thing for those in the Ruling class in practice. For the Ruling Class the only enforcement is inter-class squabbles, oligarchs shiving oligarchs thru the state.
In as much the rules that Trump is breaking might as well be a completely different concept.
No offense, but I think fetishizing movements in the imperial periphery is a way to absolve responsibility from people in the imperial core. Communism tells liberals they need to do more, Third Worldism tells Communists they need to do more. It's not a hierarchy based on who has to deal with the most suffering, it's a hierarchy of who gains more benefit from the current state of the world and therefore who has more responsibility and power to fix it. You are simply shoveling the responsibility to those who comparatively the hardest battles.
Hamas can't save us. That idea is the idea of Red Dawn -- the same silly fantasy that libs have about the poorest taking their things -- but for potential allies of the invading communist movement, rather than its enemies. It's Communist Big Mommy
