With their air defenses shredded, allies sidelined and stockpile of missiles running down, Iran's theocratic leaders face the prospect of having to submit to a tougher deal on their nuclear program as their only way out of a worsening situation.

U.S. President Donald Trump said on Monday Iran should have signed a deal with the United States on its nuclear program before Israeli strikes began and that he believes they now want to make an agreement.

The U.S. commander in chief again urged the Islamic republic to reach an agreement “before it’s too late.” Trump’s comments during the gathering of world leaders came shortly before Israel’s ambassador to the U.S. laid out what it would take from Tehran for his government to end its strikes on what he dubbed “the head of the snake.”
