The West Bank was part of Jordan until Israel stole it. Gaza was Egyptian until Israel turned it into a concentration camp. Golan is part of Syria, not Israel. Two decades of Israeli occupation in south Lebanon was the reason Hezbolla gained support. Russian Jews and those from Eastern Europe came in to settle the new nation of Israel after WW II, it is not any more a nation than those other Middle East nations, like Iraq where European outsiders drew the boundaries.
HAD the U.N. followed, and enforced a two-state solution using boundaries like the Peel commission suggested decades earlier, a more “peaceful” solution, including joint administration of Jerusalem (which Israel refuses to accept, at least the right-wingers in Likud) to create greater equality for the people whose families had occupied the land for two millennia.
