THE impact of President Trump's first 100 days will perplex academics and political commentators in the months and years to come (“The best ever, bar none - and also an irrelevance”, The Herald, April 27). His supporters do not seem to realise that his flurry of Executive Orders has not been funded by Congress. More worryingly, his constant, belligerent tweets about North Korea have only inflamed an already tense standoff. His exhortations to the United Nation about Syria and North Korea fly in the face of the power of the veto which can be exercised by Russia and China in the Security Council.

No textbook on the art of leadership will emphasise narcissism and unpredictability as essential qualities for any occupant of the White House.

President Trump's popularity rating is at a very low 42 per cent, and his report card at this early juncture would surely say: "Considerable scope for improvement. He must appreciate that an organisation will seldom, if ever flourish, unless it is based on the strictest integrity. "

GIVEN that Donald Trump never sells himself short with regard to self -praise, I believe that it is too early to determine his place in the league table of American presidents. After all, President John F Kennedy, now much esteemed as a game-changing president, during his first 100 days gave the go-ahead to the CIA’S disastrous invasion of Cuba at the Bay of Pigs and began to deepen the US military involvement in Vietnam. Let us wait and see how The Donald shapes up in what remains of his spell in the White House.
