But Trump's bark has not, as of yet, been met with much bite. Trump quickly caved in support of the One China policy; an adviser has admitted Trump might merely "review" and "renegotiate" the Iran deal. Iran's Atomic Energy Organization head Ali Akbar Salehi, in fact, said he didn't think the nuclear deal would see "any serious impact" from Trump's presidency. And it remains to be seen whether Trump will actually press forcefully enough, either diplomatically or militarily, to tame North Korea.
