On Friday, January 20, 2017, Donald John Trump was inaugurated as the 45th president of the United States in what for some was not so much an occasion for celebration as one of trepidation.

That raises the question: Does Trump have what it takes, in his words, to "Make America Great Again?" the books tells you the great achievement that will return trump back to white house by year 2020.
