The most dangerous moment of the Trump presidency will arrive when he who is constantly gnawed by insecurities and the fear of not seeming what he is not (“strong”) realizes how weak and childish he seems to all who cast a cool eye on Singapore’s aftermath. The danger is of his lashing out in wounded vanity. Meanwhile, this innocent abroad is strutting toward a meeting with the cold-eyed Russian who is continuing to dismantle Europe’s geographically largest nation, Ukraine. He is likely looking ahead to ratcheting up pressure on one of three small nations, Lithuania, Latvia, or Estonia, each a member of the NATO alliance that, for the first time in its 69 years, is dealing with a U.S. president who evinces no admiration for what it has accomplished, or any understanding of its revived importance as the hard man in Moscow, who can sniff softness, relishes what Singapore revealed.
