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 Donald Trump said Iran was “very close” to having a nuclear weapon on June 17 while taking questions from reporters on Air Force One.

Trump has said for days that Iran should make a nuclear deal with the U.S. But his message became more dire as he warned the Iranian capital's roughly 10 million residents to flee in the dead of night.
