I am systemically advised against giving the correct answer to this question, and am emphatically not advocating for said correct answer.

Go to anti-war rallies so politicians will show how unpopular the war is (they might not care anyway). If you're talking about sending weapons instead of money, unionizing workers in weapon factories and getting them to go on strike would probably be the best choice.

Supporting Israel has to become socially unacceptable like supporting South Africa was in the last years of apartheid.

Boycotting corporations as an individual is obviously useless, but if you work in an industry that manufactures or transports weapons/ammunition/etc. to "Israel", you can educate your coworkers and help organize a strike or transport blockade. If not, you can try to educate those who do work in such an industry. If neither is a feasible option, attending protests and spreading propaganda in other ways might help radicalize others. You could attempt industrial sabotage (in Minecraft), but if you're in a position to do so, you probably work in that industry and can make better use of your time organizing

Disrupt the system enough to demand concessions. Those flight delays on the biggest travel of the year was probably a step in the right direction
