North Korea on Sunday blasted President Obama, calling him a “loser” who is preoccupied with hostilities against Pyongyang.

{mosads}”The recent wild remarks made by Obama are nothing but a poor grumble of a loser driven into a tight corner in the all-out stand-off with the DPRK,” an unidentified North Korean foreign ministry spokesman told the Korean Central News Agency, according to South Korea’s Yonhap news agency. “This is little short of admitting himself that the U.S. lacks ability to stifle the DPRK and that a military option is not workable,” the official added.

In an interview on YouTube following his State of the Union address last week, Obama said, “the Internet, over time, is going to be penetrating” North Korea and will lead to its collapse.

Obama called North Korea the “most isolated, the most sanctioned, the most cut off nation on Earth.”

The North Korean foreign ministry spokesman also said the U.S. is mistaken if it believes it can stifle Pyongyang with sanctions and pressure, Yonhap reported.
