Israeli officials have told the Trump administration they do not want to wait two weeks for Iran to reach a deal to dismantle key parts of its nuclear program and that Israel could act alone before the deadline is up, two sources said, amid a continuing debate on Trump’s team about whether the US should get involved.

The two sources familiar with the matter said Israel had communicated their concerns to Trump administration officials on Thursday in what they described as a tense phone call.

The Israeli officials said they do not want to wait the two weeks that US President Donald Trump presented on Thursday as a deadline for deciding whether the US will get involved in the Israel-Iran war, said the sources, who spoke on condition of anonymity. The Israeli participants on the call included Prime Minister Benjamin Netanyahu, Defense Minister Israel Katz and IDF Chief of Staff Lt. Gen. Eyal Zamir, according to a security source.

The Israelis believe they have a limited window of opportunity to move against the deeply buried site at Fordo, the crown jewel of Iran’s nuclear program, said the sources. The United States is the only country with the bunker-busting bombs powerful enough to reach the facility, which is dug into the side of a mountain.

The report came as reports on Saturday said that the US was moving B-2 bombers to the Pacific Island of Guam, reinforcing the possibility that the US could participate directly in an attack.
