If you’re outside the US, American politics is the politics of empire and it doesn’t matter which party is in power. From Caitlin Johnstone at caitlinjohnstone.com:
When you look at US politics, it appears as though there are two mainstream political factions that very strongly disagree with one another. “Divided” is a word that comes up a lot. “Polarized” is another.
It is of course true that a whole lot of emotion flows between these two factions, and most of it is indeed negative. The hot topics of any given news cycle in America will typically involve more than one story pertaining to the vitriolic enmity between them.
But beneath all the hurled insults and heated debates, these two factions are actually furiously agreeing with one another. They’re agreeing the entire time.
They agree that the US government should remain the center of a globe-spanning empire; they just angrily quibble over a few of the details of how that empire should be run, like whether or not the Saudi crown prince should have received some small consequence for dismembering a Washington Post reporter with a bone saw.
They agree that the US should remain the earth’s unipolar hegemon at all cost; they just loudly bicker over some of the specifics in how it should look, like whether there should be the names of Confederate generals on its military bases.
They agree that there should be a massive US military presence around the world; they just furiously dispute small particulars like whether a few thousand of those troops should remain in Germany or be moved to Poland.
They agree that there must be endless mass military violence to uphold the US-centralized empire; they just make a big show of debating whether that military violence should be more focused on Syria or Iran.
They agree that it is necessary to menace the entire planet with nuclear weapons while ramping up aggressions against other nuclear powers; they just rage back and forth about whose finger should be on the button.
