Trump sees Pyongyang’s nuclear arsenal as the greatest danger facing U.S. national security, but he isn’t just inexperienced when it comes to foreign policy — he often veers into downright clumsiness. A recent example came two weeks ago, when he announced that he had directed a U.S. aircraft carrier to head toward North Korea as a warning — even though the vessel was actually heading in the opposite direction to take part in a maneuver near Australia. Whether it was a bluff or whether Trump had misunderstood something remains unclear — even as the vessel, the USS Carl Vinson, is now steaming toward Korean waters — but it does show the degree to which things can go wrong under this commander-in-chief.Following the numerous failures and defeats he has suffered early on in his presidency, Trump badly needs successes to present to his supporters as he passes the symbolically important 100-day threshold. An aggressive stance toward North Korea at least gives him the appearance of resolve and Trump hopes to demonstrate that he is able to stand up to the Pyongyang dictator. When he launched 59 missiles at Syria earlier this month, he received praise even from commentators who don’t normally have a kind word to say about this president. Because of Trump’s apparent addiction to public acclaim, it isn’t difficult to imagine the conclusions he drew.
