Trump warns Iran's 'clock is ticking': Move 'fast' or 'there won't be anything left'

"TIME IS OF THE ESSENCE!"

"Our eyes are also open regarding Iran," Netanyahu said Sunday morning, as translated from Hebrew. "I will speak today, as I do every few days, with our friend President Trump.

"I will certainly hear impressions from his trip to China, and perhaps other matters as well. There are certainly many possibilities, and we are prepared for every scenario."

Intelligence officials believe that the Iranian regime thinks it can delay developments and stretch the crisis out for at least two more weeks, so that the situation could become more difficult for Trump to restart the military campaign, both politically and operationally.

The impact of the U.S.-led blockade is becoming increasingly visible inside Iran, according to a senior Israeli official, early signs of a developing fuel crisis emerging over the weekend - including long lines at gas stations and growing public discontent over fuel shortages and distribution problems.

"It's getting exponentially worse," the official added.
