Where is your proof of so called "Terrorism" by the founders of Israel?
Um, it's pretty well documented by the British and at the UN, in their reports of the Stern Gang terrorism. Avram "Yair" Stern - who is pretty unequivocally one of the founders of modern Israel - blew up British military vehicles and bases, sabotaged rail lines, shot at trains, blew up a mine, destroyed international telegraph lines, attacked police stations, and robbed banks. His Lehi fanatics were completely unconcerned about civilian casualties (including any Jews who did not support them) and willing to ally with any military power that would send them weapons, including the Nazis.
This is all a matter of record and the state of Israel does not contest any of it; so why are you claiming otherwise?
The USA has terrorists among our founders, too. Ethan Allen and the Green Mountain Boys come to mind... although I guess they weren't in the same league as Stern.
