The bombing of Nazi Germany in return had the same effect. Due you think people will flock to an enemy, that bombs them every night? No, they will put all their strength into trying to prevent the bombs from falling down in the first place.
I mean the US was seen as a favorable enemy, but that was more to the USSR being way worse and due to the post-war behaviour. I still see the effects of e.g. WW2 allied bombing, when walking through my city. And the railway system in (East) Germany has never recovered and this is still causing problems.
