From Jonathan Bernstein:
From the perspective of presidential power, President Donald Trump’s decision to withdraw from the Iran deal seems to offer little upside and quite a bit of downside risk.
The move adds all sorts of uncertainties, but doesn’t appear to satisfy any significant demands from Trump’s coalition. And it inflicts further damage on the president’s professional reputation, which has already been shredded by some of his other actions. The combination stands to make Trump an even weaker president than he already is.
