A recent poll shows that the U.S. public is strongly supportive of the U.S. military’s Asia pivot:

New analysis of the Chicago Council survey results on Asian issues by Dina Smeltz and Craig Kafura shows that over three-fifths of Americans now express support for the U.S. rebalance to Asia and that American favorability toward its two closest American allies in the region, Japan and South Korea, have reached their highest levels since the poll was started. Sixty-two percent of Americans recognize that Japan is one of America’s top ten trading partners and 64 percent support a long-term U.S. military presence in South Korea. (Defense One)

Though a high percentage of the public supports troops in Korea, less people have a favorable opinion of South Korea compared to Japan:

Analysis of the Chicago Council poll results for Japan by Michael Green of CSIS underscores the high level of trust among Americans toward Japan, rating Japan fourth globally in favorability (at 62 out of 100) behind only Canada (79), Great Britain (74), and Germany (65). …………

My review of the Chicago Council poll results for Korea shows a growing gap in American favorability toward South Korea (55 out of 100) versus North Korea, which at 23 out of 100 scored the lowest favorability among nations included in the poll.
