I’m an American residing in Israel (I’ve lived in Israel, on and off, for five years). Yes, everything you note is typical Israeli behavior, and you are not the first to notice it. Here are two theories on why this is so: First, history has taught Israel to be tough and aggressive. The country owes its continued existence to toughness and aggressiveness, and so individuals learn from this. True, this lesson is less true today than it was 20 years ago, but attitudes change very slowly. The other theory is that local attitudes teach individuals, as children, to not be suckers. Thus, everyone always pushes everyone to ensure that no one will take the slightest advantage.
