alt Hacker NewsAs a German living in Berlin it's still pretty normal that once in a while WW2 bombs are found during construction. Heavy bombs that didn't explode probably penetrated the ground quite a bit so when rebuilding it was probably just easier to just leave them there. That's just a guess.
There are also still bombs and grenades in the rivers. There are some magnet fishing YouTube channels where you can occasionally see them pulling up stuff like that.

My take (equally guessed): Among the literal rubble spread all over the cities, people constructing everything back up with whatever means possible couldn’t even recognize a mostly buried object as a bomb (instead of just more scrap from a collapsed building).
So less of an active decision to not deal with it, rather one out of necessity and/or not knowing about them, perhaps?
