I agree that Trump does not present a very sophisticated, intelligent and statesman like image. He is brash, has knee jerk reactions, populistic and so on.
But on the plus side, he is spontaneous, says what he thinks and takes a common sense approach. That has its freshness and usefulness....however uncomfortable it may make some people feel.
Cautious diplomacy, political correctness, sweet talk and impotent intellectualism can be tiresome.
