Vietnam and Iraq are two nation states and had populations between 25-30m at the time US waged war in those countries. Gaza is a narrow strip of 139 square miles of land with 2mn people packed together like sardines, who have no sovereignty, have been under an economic blockade since 2007, and whose rulers Hamas have no conventional military to speak of. These two are not comparable, I don't know why people keep pointing to the destruction of Nazi Germany and Japan as the benchmark of whats acceptable in Gaza, its quite insane tbh.
