The Washington Post reports:

President Donald Trump launched Saturday’s wide-ranging attack on Iran after a weeks-long lobbying effort by an unusual pair of U.S. allies in the Middle East — Israel and Saudi Arabia — according to four people familiar with the matter, as Israeli and U.S. forces teamed to topple Iranian Supreme Leader Ali Khamenei after nearly four decades in power.

Saudi Crown Prince Mohammed bin Salman made multiple private phone calls to Trump over the past month advocating a U.S. attack, despite his public support for a diplomatic solution, the four people said. Israeli Prime Minister Benjamin Netanyahu, meanwhile, continued his long-running public campaign for U.S. strikes against what he views as an existential enemy of his country.

The combined effort helped lead Trump to order a massive aerial campaign against Iran’s leadership and military, which in its initial hour led to the death of Khamenei and several other senior Iranian officials.

The attack came despite U.S. intelligence assessments that Iran’s forces were unlikely to pose an immediate threat to the U.S. mainland within the next decade. Saturday’s attack on Iran was a break from decades of U.S. decision-making to hold back from a full-scale effort to depose the regime of a country of more than 90 million people. It also marked a stark shift from Trump’s own previous military forays, which until now have been far narrower in scope.
