During the Cold war, by default, Western nations fought against communist revolutionaries any where in the world.
Before that, Western nations sided with the military dictatorship of Chiang against the Mao Zedong revolutionaries. Same story in other parts of Asia, South American and Africa.
It is now 20 years since the Cold war ended. It takes that long for the West to finally realise it makes more sense to fight along with the people against dictatorships and tyrants than to side with dictators and tyrants to fight the people.
