Unipolar Hegemony Is A Freakish Historical Aberration

The US is indisputably the most tyrannical regime on earth. Only the US is instigating wars around the world, circling the planet with hundreds of foreign military bases, starving populations with massive unilateral sanctions and blockades, and working to destroy any nation which disobeys it. No other government has spent the 21st century killing people by the millions in wars of aggression; only the US has. Continually trying to destroy anyone in the world who doesn't obey your dictates is as tyrannical as it gets.
If you point this out you'll get people telling you that if it wasn't the US doing those things it would be someone else, but that's ridiculous. There has never once been a unipolar planetary hegemon at any time in human history until three decades ago. People look at this freakish historical aberration and talk about it as though it's some immutable quality inscribed in adamantine upon human DNA strands. 
A single power structure dominating the planet is very much the exception, not the rule. A multipolar world is the norm in the same way a cancer-free body is the norm; you'd only assume cancer is the norm if you'd only ever seen one human body and it was a cancer patient. That doesn't mean a future multipolar world order would be perfect or free from problems, it just means the expectation that the US unipolar hegemon would be replaced by another one is based on absolutely nothing and is refuted by all historical precedent. And as an added bonus we'd no longer be trapped in this horrifying situation where a planetary empire is continually trying to shore up disobedient nations like Russia and China while brandishing armageddon weapons with increasing aggression.
