So whatever it has done, it cannot possibly be worse than pre-war
“Terrorist” groups Irgun, Haganah, Lehi all became part of Israeli government and army post 1948. Israel has mandatory military service for its citizens.
Irgun and Lehi were both offshoots which can be categorized as terror organizations, however they were very small, with a few hundred members and never reached the size or level of support of any Palestinian organization
While the Haganah formed most of the IDF leadership, the new country civilian leadership was based on the Jewish Agency which predated the Haganah and had completely civilian leadership.
There are many other differences between Hamas and these organizations, but in general this is an invalid comparison
There are certainly many angry Palestinians before and after but this is foreign meddling through and through. Hamas would not exist in this form and have done the things that it did otherwise.
Hamas is not a rational actor. Their stated goal is to destroy Israel and kill every Jew. That's it. There is no scenario in which they are going to stop hating Israel. They don't care if every Palestinian also gets killed, if they get to destroy Israel it's worth it to them.
It feels like almost ever day that I see a video of a Palestinian's home in the West Bank being demolished or a Palestinian family being harassed by armed settlers
Israel would have created multiple generations of emboldened anger and hate against themselves if they failed to respond to the massacre and mass kidnapping.
I'm not comparing Israel or Palestine to Nazi, it's just a bitter fact that war always create anger and hate. Something had to be done though?
Will we (and/or Israel) do the same for Gaza? What about Lebanon and Syria?
We certainly failed at this in Iraq and Afghanistan, did we learn any lessons? Will the incoming US Administration fumble this opportunity?
As Stephen Kotkin likes to say "You can win the war and lose the peace. You can also lose the war and win the peace"
What comes after the war is as important, maybe more so, than the war itself
