Israel has been a huge crybully virtually since it was founded. It’s been annexing Palestinian land from the beginning, running a shitty apartheid state, committing ongoing slow genocide on the Palestinian people, then crying the innocent victim whenever they hit back - and guzzling unlimited billions in US military aid to do so.
Hurt people hurt people, and oppression breeds radicalism. Hamas are not nice people, but they’re from a place where nice people don’t live long enough to matter. As with any abusive relationship, there’s going to be toxic coping mechanisms as a result, and it’s important to acknowledge that it’s not okay to do those things.
But Israel (the country, not the people) sure as hell rakes in a lot of money and influence from being constantly under threat from the mean nasty baddies that they just have to keep oppressing and killing and oh look more money.
