Can the US-Japan alliance survive Trump?
Concerned. Anxious. Confused. Perplexed. These are the most common adjectives I heard in Tokyo from Japanese officials and experts who are trying to understand the Trump administration's approach to foreign policy and what it might mean for them.
They are concerned about President Donald Trump's statements during the campaign - and for the last 30 years - denigrating U.S. alliances and bashing Japan, and wonder whether Trump understands the value of the alliance at all.
They are concerned about Trump's transactional approach and fear that he will link economic and trade issues with security, holding the alliance hostage and putting the credibility of U.S. commitments in doubt.
They are concerned about what "America First" means, especially for U.S. commitment to the Asia-Pacific region, and whether U.S. leadership and the U.S. presence will continue.
