S For some time now, White House insiders report, US President Donald Trump feels he has a better command of his job and even less needs advice than he does anyway. He relies more and more on his own instincts and beliefs. What that means, he has adequately demonstrated: Trump stepped out of the Paris Climate Agreement, quelled the nuclear deal with Iran and began trade wars with Europe and China. Prior to his second visit to Brussels, where the next NATO summit will take place next Wednesday, Democrat foreign policy leaders have now written a concerned letter to the White House. In it, Trump is urged to “make it clear that the United States is with and not against our oldest and closest allies.” It is only doubtful whether the President will listen.
