US President Donald Trump had serious difficulties finding and appointing a new state defense minister. Two people have already abandoned this post after James Mattis left.
According to Politico, the leader of the United States made a proposal to become the head of the Pentagon to former Senator John Kyle and retired general Jack Kean. By the way, the latter quite often provides advice to the president of America.
Recently it was reported that the duties of the chief of the defense department of the United States are performed by First Deputy Minister of Defense Patrick Shanahan.
The fact that James Mattis decided to leave the post of Minister of Defense became clear on December 21, 2018. This decision was caused by discrepancies with the country's leader, as stated in his address to the US leader.
James Mattis became head of the department on January 20, 2017. Before that, he served in the US Marine Corps and participated in operations in Afghanistan and Iraq. He supervised the modification of the armed forces and headed the Central Command of the US Armed Forces. This command is in charge of operations in the Middle East, East Africa and Central Asia.
