I would not. As bad as it is to refuse entry to a person based on uncorfirmed suspicion, refusing exit is a whole order of magnitude worse.

No, and I honestly can't think of how you interpreted that. Please explain.

EDIT: Oh, wait, I think I get it: you see the U.S. as a safe heaven, a place people should go to escape dictatorships, a place where their rights would be respected. Is that it?

Iranian government officials have repeatedly stated that their goal is to wipe Israel off the face of the earth. Even if you don't believe them, their nuclear weapons could end up in the hands of terrorists who do have that goal.

If you support the US allowing Iranian nuclear scientists to return to Iran, you are supporting that policy.

As a side note, an advanced Iranian nuclear state would likely entail a massive war in the Middle East to stop them, so there's also that.

This is what I find surprising about security checks, don't quite understand. When I entered Israel I was out hailing a cab within minutes of debarking my flight. When I was leaving, they had me detained and searched thoroughly. I couldn't understand why they let me enter in the first place if I was such a suspect personality.

Travelling into/out of Israel the extra security checks are all about getting on an airplane (due to historical attacks on air travel). Getting off the plane at Ben Gurion Airport is always easy, but you probably went through extra screening getting on that plane at the other end (in my experience, usually done by Israeli security guards at foreign airports).

On the way out, Israel not only cares about their security checks, but whether you're going to cause other countries to doubt their checks.
