Why doesnt Allah (SWT) destroy the Tyrants?

I heard about a tyrant called Nimrood that challenged Allah and tried to fight the Almighty, but then Allah (SWT) sent a mosquito which killed Nimrood, why doesnt this happen to tyrants that try to challenge the Lord nowadays, i always hear that nations were destroyed for doing evil centuries ago, but there r still nations to this day that r still corrupt and evil, why doesnt Allah (SWT) destroy them just how Nimorood was desttroyed or how Sodom was destroyed, etc etc?
