Going to fight against Nazi Germany for comparison of porportional counter attacks is really dumb when the Nazis killed more civilians than all their enemies during WWII combined. And it is not like the russians did not kill those in retaliation aswell, it was just impossible to catch up (we are going to ignore what Stalin did outside of fighting germany for this comment). Comparing a power capable of subjugating nearly a whole continent in the span of some months (all while planning and executing the murder of millions of civilians) with hamas got to be a bad joke.
