President Donald Trump arrived in Washington, D.C., early Tuesday morning after abruptly leaving the G7 summit in Canada to address the escalating conflict between Israel and Iran.

DUBAI, United Arab Emirates (AP) — Israel appeared to be expanding its air campaign on Tehran five days after its surprise attack on Iran’s military and nuclear program, as U.S. President Donald Trump posted an ominous message warning residents of the capital to evacuate.

President Donald Trump is under fierce pressure from inside Israel and his own MAGA base as he ponders the most fateful national security decision of either of his presidencies — whether to attempt a killer blow against Iran’s nuclear program.

President Trump is trapped between the “America First” isolationists and others in his party who are cheering on Israel’s strikes against Iran.

“They should now come to the table to make a deal before it’s too late. It will be too late for them. You know the people I was dealing with are dead, the hardliners,” he added. The strikes killed the head of Iran's Revolutionary Guard Corps, and the country's top two military officials, in addition to several nuclear scientists.

Israel’s attack on Iran was long in the making – the result of years of meticulous planning by Israel and days of high-stakes talks between Tel Aviv and Washington, officials told CNN.
