I'm afraid that's nonsense. Israel has defeated their neighbours against appalling odds more than once. They are also a nuclear power. They aren't going anywhere.
They don't really care what we think about them. If they wanted to turn the Gaza strip into glass, they would do it.
The truth is they don't.
It's a simple statement but it's true, if the Palestinians put down their weapons, they would lose land and maybe receive some poor treatment (which I utterly condemn), but they would continue with their lives. If the Israelis put down their weapons, there would be a second Holocaust the like of which the world has never seen.
Neither side is 'good', but they certainly aren't morally equivalent on any level.
