Israeli experts in Israel and A mystery

It always strikes me as odd when Israeli experts in Israel object to the U.S.'s belligerent posturing in the Middle East, while the most vocal U.S.-based Israeli supporters (see Joe Lieberman, for example) support it:

JERUSALEM - After years of supporting the Bush administration's policy in the Middle East, a growing number of Israelis are openly criticizing the United States for creating more, not less, danger for Israel.

Israeli experts contend that American policies have destabilized Iraq, emboldened anti-Western forces from Iran to Lebanon and paved the way for militant Islamists to gain control of the Palestinian Authority.

"The threats to Middle East security and stability worsened in 2006," experts at Tel Aviv University's Jaffee Center for Strategic Studies recently warned. "The American failure in Iraq has hurt the standing of the U.S. in the Middle East."

Perhaps most strikingly, in their annual evaluation of the situation, the Israeli analysts concluded that it was better for the United States to get out of Iraq than to add troops, as President Bush is proposing.

This is true on many fronts. There's a lot of debate within Israel about the appropriateness of that country's policies on settlements and other Palestinian matters, but any debate of those policies here is considered anti-Semitic and nearly traitorous.

I really haven't figured out why this is. Is it because some Jews who live here are secretly ashamed of themselves for not having moved to Israel and want to prove their loyalty through excessive pro-Israeli noise-making? Somehow that doesn't seem sufficient to explain it.
