Old countries like the UK or France or Germany have learnt over rhe centuries the damage nationalism can do. It makes you feel great, proud of who you are, makes you feel special and strong, but ultimately it can also lead to hatred, violence, self-destruction. Jews haven't had a chance to experience this over the centuries of the disapora, and in the early years of Israel, they were probably too worried about Israel's mere survivial to waste too much time on it. Now,though, that Israel is the regional superpower they can let it all hang out and really binge on nationalism. Feels good. And better still, they have another race and neighbours they can look down on, and there's a vague threat from Iran which can give nationalism that extra little spice of danger! It's all higely exciting and intoxicating and under its influence, normally mild-mannered people do all sorts of stupd things like insulting your parents and wishing you death from cancer.
