Good column, and conservatives should  be pleased the RG added another conservative columnist with  Jennifer Rubin.  This makes her devastating account of Trump's poor     leadership even more significant, especially combined with Kim Jong Un's own irrationality. 
This got me to thinking back at Reagan and Gorbachev, and how they negotiated an end to the Cold War.  While I didn't agree with many of Reagan's domestic  policies, he and Gorbachev were a class act when they finalized the understanding of MAD, Mutually Assured Destruction, to begin the stand down from nuclear saber rattling.  
As there's been no use of the atomic bomb since 1945, there are few Americans alive who remember that shocking experience. I'd encourage everyone to look carefully  at the August 6 1945 paper in today's (Th.) RG.  Note Truman stated we dropped the bomb on Hiro Shima, "an important Japanese army base."    Actually, the casualties were overwhelmingly   civilian.
