The IDF is effective only because Israel itself is basically crazy. They would blow themselves up rather than succomb to Arab control. When was the last time the IDF engagaged in general warfare? Today all they do is peacekeeping/low intensity conflict stuff. Of course they have a method of dealing with the enemy that would land the U.S. in the middle of a major sh1t storm of international b1tching. The IDF is pretty ruthless, not so much effective.
