Yeah, if the pro-Palestinian movement was a non-violent resistance movement I'd be on board 100%. But unfortunately that's not what it is.
Odai Nasser Saadi Al-Rubai is someone we should support, someone who wanted peace. But he's dead now and those who claim to want peace for Palestine seem to want to erase him from existence. He was inconvenient to their narrative so they will pretend he didn't exist.
How can someone claim to be to be pro-Palestinian if they have no empathy for Odai Nasser Saadi Al-Rubai, a Palestinian that wanted there to be an end to this war? It doesn't seem like a pro-Palestinian movement to me, it just looks like an anti-Israel movement.
Yes, I mentioned it takes a long time - generations. And if by "let him be" you mean nobody went to war with Franco, then yes, that's why it's Plan A, the option that doesn't involve all out war.
Are you looking for an option where the US can quickly end it's fascist movement? Unless you have a time machine and can go back in time and convince more people to vote for Kamala Harris, then I got nothing for ya. Best case is, the US is Franco's Spain and it's going to suck for decades. Worst case the US is WWII Germany, and it's going to really suck, though for a much shorter period of time.
