Trump indeed looks like an ignorant fool, however I must recall that after one year in office, despite his barking against north corea he has bombed far more people and countries than his predecessors.
Trump is just engaging in verbal confrontations. On the other hand, if Hillary was elected as the president, then she would have already started military invasions against nations such as the North Korea, Iran, and Russia. So at least in this regard, Trump is much better than Hillary. Also, we should not forget that the American economy is doing exceedingly well now.
