Yes, Jewish people suffered greatly in the last century. Yes, there people in certain countries/religions who actively want to kill Jews or at least Israelis. Yes, Israel is a majority Jewish state.

But.

No, a past genocide does not give a free pass to execute a new one. No, murdering thousands in collateral to catch the ones who might be dangerous is not acceptable (not to mention the executions etc of obvious non-combatants). No Israel does not speak for all Jewish people nor have justification to excuse their behaviour/crimes as such. Also, yes the Israeli government/leadership is corrupt as fuck, uses war to dodge accountability, and is involved in a lot more terrible acts than "just" the ones in Palestine.

Honestly, when Mossad was blowing up pages and mobiles I thought that was great. It was strategic, effective, and we'll targeted at the actual terrorist leaders/allies rather than causing mass casualties.. they obviously have the capability to be much more surgical in their responses, so mass-bombings etc seem that much more like war/hate crimes. Doing this just creates more hatred, which leads to more terrorists and a continual cycle.
