Not surprised about this. George Bush withheld the bunker busters, so no surprise on Obama withholding strategic weapons needed for Israel to attack Iran.
Israel will be forced to use mini-nukes, I guess, to penetrate the underground nuclear sites.
I pray Israel can handle the other fronts as well, from Syria and Hezbollah, without the weapons from the U.S. Unfortunately, the article says that Israel needs certain types of missles and essential weapons systems for use against Syria and Hezbollah as well.
