When asked whether to consider dismissing Defense Secretary esper at a news conference on Saturday afternoon local time, trump replied, “I’m considering firing everyone.” There are differences between trump and Defense Secretary esper on a number of issues. Recently, a source disclosed that trump is considering replacing the defense chief after the election. The relationship between trump and the military leadership has been fluctuating since he took office. In December 2018, he suddenly announced the withdrawal of US troops from Syria, and Matisse then resigned. Patrick Shanahan took over the post of acting defense chief, and was forced to give up “becoming a full-time official” because of the exposure of the divorce scandal. The former defense chief Donald Rumsfeld and Robert Gates have served for five years respectively since 2001, and since then they have served for no more than two years. If esper leaves in November, his term of office is only one year and four months, and he will become one of the shortest serving defense secretaries in the United States in decades.
