President Donald Trump is a unique political figure, both his admirers and detractors would agree. But as he decides whether to become directly involved in Israel’s military strikes against Iran, some comparisons can be made to several of his predecessors.

Iranian officials have denied trying, but multiple alleged conspirators linked to Tehran have been charged over attempted plots against the U.S. President.
