It’s exactly the policy that Israel has developed itself, because it knows what’s the best policy for the situation that they’re in.
Israel doesn’t practice “knee-jerk” reactions towards their enemies out of stupidity, like some people post here - and that’s because their very survival as a people — and — as the “homeland for the Jews” is at stake. Israel knows how to take care of itself.
Their survival is continually threatened because they keep being PC. Sorry if history upsets you so. But warfare isn’t kneejerk. Combatants die. Supporters of combatants die.

When you keep rebuilding your enemy’s forces, you never stop fighting. Or win. Eventually your enemy kills you with your own tools and you are gone.
