"By meeting with North Korean leader Kim Jong Un, Trump promises to wave his hand and create peace where before there was nothing but strife and dissension, writes John Feffer (Two-Faced Trump: Peace in Korea, World War in the Middle East Foreign Policy in Focus 05/06/2018). "At the same time, Trump the Destroyer has pledged to take the United States out of the Iran nuclear deal and bring the world that much closer to apocalypse."
I'm very dubious that Trump will be able to secure a nuclear agreement with North Korea. He's so impulsive and has no interest in policy details. And the global nonproliferation project has been compromised by the US/NATO attacks on Iraq and Libya and by the Russian confrontation with Ukraine and the annexation of Crimea. And, as Feffer notes, "In light of Trump’s attitude toward previous U.S. pledges to Iran and the presence of John Bolton as the new national security advisor, any promises from Washington are worth less than the 140 characters they’re tweeted in."
But for whatever reason, he presently likes the image he's projecting of a peacemaker in Korea and a war hawk in the Middle East. As Feffer puts it, "like the rooster who believes that his crowing has caused the sun to rise, Trump took full credit for North Korea’s turnabout at the beginning of 2018." But it will take much more than Trump puffing about how great he is to get a meaningful nuclear agreement with North Korea.
