Every place has been unstable at some point.
And every place actively destabilized by an empire is definitely unstable.
The amount of coups directly planned and executed or supported by the US military/intelligence/lobbying apparatus in south America and the rest of the world is incredible.
And then the presidents have the audacity to say that it is the right and responsibility of the locals to govern (as said by biden on Afghanistan exit).
It truly has been the most exploitative empire ever. I hope the Chinese do better. We'll find out.
You're replying in good faith to someone who ignored the main point of GP (an empire actively disrupting a region) and just said "every place has been unstable" (without even taking century-level timescales into consideration).
I see no evidence at all they will do better. Rather the opposite.
