Geopolitical decisions aren't made by countries, they are made by individual people.

Sometimes those people are a plurality that organically endorses that decision and votes some representative in. Sometimes those people are a plurality that has been brainwashed by compromised media to do it. Sometimes those people are just a small ruling elite that get voted in by people who didn't think very hard about those particular geopolitical decisions and just want, I don't know, their political and cultural enemies brutalized and $1.99 gas.
