Yeah they definitely were, and that's awful, all genocide is awful.

Its hard to say how far back to look, one would hope as generations continue hatreds of past injustices (if anything was done to ease/reduce/eliminate) those injustices would start to simmer down on all sides.

Unfortunately very often prejudices are passed down to the next generation which just starts the cycle all over again.

Regardless, the Holocaust was horrible no question but that doesn't then justify the government of Israel getting away with war crimes, nor does me saying that justify in any way the horrible things Hamas has done. However it is important to understand context especially in the more recent past.

Understanding how and why the Israel/Palestine conflict has simmered would lead to how and why Hamas was formed in the first place, similar to how looking at America helped formed Al Queda to overthrow the Soviet-backed government of Afghanistan
