Amazing what Obama is willing to give up in order to secure 'his' legacy issues. 60 years of post war Asian defense strategy thrown out the window. I don't see this ending well. Japan a has a deep militaristic underbelly and most japanese hate their regional neighbors (South Korea, China). They are our allies but this increases instability in Asia enormously and could lead to a regional arms race between China and Japan and greatly increases the risk of a military conflict in Asia in the next 30 years.
