A government can tyrannize both at home and abroad. From Caitlin Johnstone at caitlinjohnstone.com:
You get a lot of moral clarity when you realize that the US government is the most despotic and corrupt regime on the entire planet by a very wide margin. This clarity informs your perspective in a way that helps you see through a lot of the propaganda narratives that are laid over the public’s vision about what’s going on in our world.
Whenever I say the US is the most tyrannical regime on earth I get a lot of objections from people, and these are always people who simply haven’t thought very hard about the horrific realities of US foreign policy. Sure you can name some governments who are more brutal and oppressive toward their own citizenry than Washington, but you can’t name any who are more brutal and oppressive overall when you zoom out and look at the big picture.
The United States is currently circling the planet with hundreds of military bases and waging wars which have killed millions and displaced tens of millions just since the turn of this century. Its sanctions and blockades are starving people to death en masse every single day. It works to destroy any nation which disobeys its dictates by toppling their governments via CIA coups, proxy armies, partial and full-scale invasions, and the most egregious number of election interferences in the entire world.
