if you care to actually know what the Church thinks I'd do research, otherwise you're just going to get people's own reasoning.

God was fairly brutal in most of the Prophet's books because there were a lot of judgments, there were very evil nations that would fall in to witchcraft, idolatry, murder, etc., and they would do this for a very long time.

God is extremely patient and wants all to repent, He at one point waited for four-hundred years for a nation to repent, which they did not, so they got annihilated. The judgments back then are not much more different than the ones today, that happen all the time throughout history. Detroit was a palpable judgment in our own backyard, the city got decimated because of murder and gang violence. That didn't even take that long compared to other judgments.

God has always been a God of peace and love, we live in a time where the first world is very peaceable, so we aren't familiar with the depths of human wickedness. A good majority of nations have been very evil, you don't get to kill, steal, and destroy without consequences.

God isn't unjust either, which seems to be people's worry with people/nations getting destroyed. People who fear God don't end up in Hell.

I disagree with us not being familiar with the depths of human wickedness, that is only true in the grand scheme of things. Otherwise i would say people and especially goverments today are very wicked, even if not as wicked as those places that God destroyed. I have often wondered when will God deliver judgement again, California for examples seems like a prime Sodom to destroy.
