The good thing about John Bolton, President Trump’s new national security adviser, is that he says what he thinks.
The bad thing is what he thinks.
There are few people more likely than Mr. Bolton is to lead the country into war. His selection is a decision that is as alarming as any Mr. Trump has made. His selection, along with the nomination of the hard-line C.I.A. director, Mike Pompeo, as secretary of state, shows the degree to which Mr. Trump is indulging his worst nationalistic instincts.
Mr. Bolton, in particular, believes the United States can do what it wants without regard to international law, treaties or the political commitments of previous administrations.
He has argued for attacking North Korea to neutralize the threat of its nuclear weapons, which could set off a horrific war costing tens of thousands of lives. At the same time, he has disparaged diplomatic efforts, including the talks planned in late May between Mr. Trump and the North Korean leader, Kim Jong-un. He not only wants to abrogate the six-party deal that, since 2015, has significantly limited Iran’s nuclear program; he has called for bombing Iran instead. He has also maligned the United Nations and other multilateral conventions, as Mr. Trump has done, favoring unilateral solutions.
