During the presidential transition, the president must ensure the current affaires. Since November 8, 2016 and the election of D. Trump, Obama should not make any important decision. This may be against the will of the American people who have chosen a change, and impede the passing of power. Indeed, the decision to punish Russia or the change of the position in the Israeli-Palestinian conflict show Obama's lack of political maturity and the weakness oh the Democratic Party.
