The correct answer is: divided Congress.
In a divided Congress, one party will control one house while another party will control the other house.
Currently, the Democrats control the House and the Republicans control the Senate.
An important duty of the president is "negotiating treaties," since this duty falls to the executive branch, and the president is in charge of this branch (although this specific task is often delegated to the State Department).
War victory or even entrance into a war.
The supreme leaders of the DPRK have been Kim Il-sung, his son Kim Jong-il, and his grandson Kim Jong-un.
Hope this helps
