Israel Using a Secret War Against Iranian Nukes

I just have to wonder why this British newspaper felt a need to leak this information.

"Israel has launched a covert war against Iran as an alternative to direct military strikes against Tehran's nuclear program," Britain's Daily Telegraph said on Tuesday. "It is using hitmen, sabotage, front companies and double agents to disrupt the regime's illicit weapons project, the experts say."

Quoting intelligence experts and an unnamed former CIA agent, the newspaper said Israel's "decapitation" strategy had targeted members of Iran's atomic program, hoping to set back the country's nuclear ambitions without resorting to war.

The problem I have is that isn't this a casus belli? I mean Israel is supposed to be using spies to possibly kill scientists and sabotage facilities? You would think that was a declaration of war and Iran would strike back. This is a fine line for the Israelis to walk.

Especially when Obama is a big question mark in his support for their security. If Iran declares war on Israel citing the killing of their citizens as a casus beli will America come to their aid? What happens if Iranian planes start to pound civilian targets all over Israel and the IDF retaliates by hitting Iranian airfields? The only sure thing in that situation is an oil spike everything else is up in the air.
