Israel would beat them like a dirty rug....
Yes, but they could rain thousands of missiles on Israeli cities. And if Hezbollah does start something, Israeli needs to terminate it with extreme prejudice.
The Rabin generation were the veterans of several major but senseless wars with their Arab neighbors. They were disgusted with conflict and genuinely wished to make peace with their enemies . Many of their enemies of the Rabin generation also wished to make peace with Israel.
Unfortunately for the world, the peace brokers at the time were Bill and Hillary Clinton, both of whom were major Yasser Arafat / PLO groupies who installed Arafat and the PLO as the partners for peace and Arafat and the PLO had no desire for peace with Israel
The current generation in Israel understands that they have been cheated and the only peace process the world (except for the US under Trump) offers Israel is the Peace of the Grave
Israel has responded to provocation til now with very measured response, but the next time Israel is forced to go to war their response will be anything but measured because the current generation of Israelis is under no illusions that most of the world harbors any good will or good intentions towards Israel and most of the world would be happy to see Israel cease to exist.
The current generation of Israelis are coming to grips with the reality that the next conflict will be decisive and result in the total destruction and subsequent enslavement of the State of Israel or it will leave Israel's enemies with neither the will nor the means to ever engage Israel in a follow on war
The next Arab-Israeli conflict will for all the marbles and to the death for Israelis so Israel has not the luxury of holding back or pulling any punches
