Actually that is fake history but it's also quite irrelevant. It is quite possible to lose a war and still hate the people who won...I'm a national socialist, for example.
Actually, It is factual.... Israel did not defeat 5 of their invading Arab neighbours in 1948 with Arms provided by the US Government.. Another fact you seem to evade that when countries (especially those who initiate them) are defeated in Wars, it is the Victor who dictates terms and draws boundaries, not the losers.... A Map of Europe prior to and then after WW1 and WW2 proves as much.. No one expects the loser to like the winner, that is what's irrelevant..
