According to Haaretz, the Obama Administration will provide a “nuclear umbrella” to protect Israel:

U.S. President-elect Barack Obama’s administration will offer Israel a “nuclear umbrella” against the threat of a nuclear attack by Iran, a well-placed American source said earlier this week. The source, who is close to the new administration, said the U.S. will declare that an attack on Israel by Tehran would result in a devastating U.S. nuclear response against Iran.

This is useless for more than one reason:

1) A nuclear strike against Israel could kill almost half of the Jews in the world (as well as many Christian and Muslim Arabs) and would threaten the survival of the Jewish People. Both the State of Israel and the Jewish People are far more interested in survival than revenge.

2) Said “nuclear umbrella” is based on a faulty assumption that Iranian leaders are rational actors and would see a nuclear catastrophe as a deterrent rather than an opportunity to kill Jews and bring the Mahdi (Islamic Messiah).

I advise the Obama administration to concentrate instead on prevention of Iranian nuclear capacity.
