"All the world will stand with you together"?

LOL nope, your "plan" is what the Palestinians did after 1948, what the Irish did after the Cromwellian wars, what the Bantu did under apartheid, what Indians did under the Raj, what China did under the Unequal Treaties.

In each case, nothing changed until the oppressed were willing to organise and use force to gain leverage in negotiations.

Israel is the world's largest foreign aid recipient. End the aid, end the genocide. 

 Yes, that time Palestinian establishment of country was failed, Palestinian should try it again, all of the world will support them. 

 Palestine HAS diplomatic recognition from more countries than Israel does. They have been "trying it again" every day.

What they don't have are nuclear weapons, and friends with disproportionate power over Western politicians and media.

They're not likely to get those, either, and neither are most of the world.

What happened to Palestine could happen next to any of ~180 countries if they have something the powerful want, but don't want to pay for. 

 lol
