By today's standards, mass rapes against german civilian women by the soviet army and other allied forces[0] or bombing of various cities of no industrial importance, such as Dresden would be easily considered as war crimes.
Saying "but they were nazis" is no different that when the Hamas explains that every Israeli civilian is a soldier to justify their actions.
A lot of people say "We did Dresden" to justify Israel's crimes but they don't realize Dresden was viewed very negatively even by the allies and the people involved in the attack after the war...
The Germans weren't a stateless people who had lived under an oppressive foreign military occupation for over half a century, after getting kicked out of their homeland. They were a major world power that decided to launch a war of conquest against the rest of Europe and beyond.
These are more not remotely similar situations.
What is the ideology that is even supposed to be eliminated in Gaza? Killing people who are oppressed is not going to make them start loving their oppressors.
