US support Israeli strike, ensuring draw-in.

“CIA does not know Israel’s near term plans and intentions,” the report adds, speculating that “Netanyahu probably calculates Israel will need to strike Iran to deter its nuclear program and faces a declining military capability to set back Iran’s enrichment program.”

That the U.S.’s premier intelligence service indicated it had no idea how seriously to take Israel’s increasingly bombastic threats to Tehran means that, in all likelihood, neither does the White House. But despite this lack of clarity, Biden has not opposed a unilateral Israeli attack on Iran — and his national security adviser recently hinted at blessing it.

“We have made clear to Iran that it can never be permitted to obtain a nuclear weapon,” Jake Sullivan said in a speech earlier this month, reiterating the administration’s oft-repeated line. The rhetoric reflects what military planners call “strategic ambiguity,” a policy of intentional uncertainty in order to deter an adversary — in this case, around how far the U.S. might go to prevent Iran from obtaining a nuclear weapon. But Sullivan went a step further, adding, “As President Biden has repeatedly reaffirmed, he will take the actions that are necessary to stand by this statement, including by recognizing Israel’s freedom of action.”

Sullivan’s statement represents the strongest signal yet that the administration would not oppose unilateral action by Israel. The rhetoric has also been echoed by other administration officials. In February, the U.S. ambassador to Israel, Tom Nides, said that “Israel can and should do whatever they need to deal with [Iran] and we’ve got their back.”
