No, America has overall killed more people, largely because they have a bigger military and affect on the world. Israel, on the other hand with a weaker military has been able to execute horrors in Gaza beyond our imagination. They're government is far more on the fascist side and on the Apartheid side even compared to Trump's America.
America is also bad though obviously the Vietnam war, Korean war where America basically carpet bombed North Korea killing hundreds of thousand of civilians, and dozens of coupes and destabilization of other countries.
OH THEY WERE ARMED. Like I thought America wouldn't do this to white people just for shouting threats, but being armed makes it undeniable.
