Appeasement a policy of making concessions to an aggressive power in order to avoid conflict. Before WW2 Chamberlain tried Appeasement with Hitler, it is basically emboldened Hitler into thinking he could do what he wanted.
And yet here we are, nearly 90 years later with Trump trying to do the same thing with Putin. It makes me so mad. Putin is not going to stop with getting some additional territory, he will move onto the next country, maybe Finland want to give him a bit of their land, or maybe Poland.
I'm so bloody cross that Trump is pushing this.
