North Korea was taken off the United States’ list of state sponsors of terror in 2008, during nuclear negotiations with the George W. Bush administration. But the rogue nation is about to take back its place on the same list, thanks to President Donald Trump.

Trump announced on Monday that he will designate North Korea as a state sponsor of terrorism. The move is designed to further isolate the country for its pursuit of nuclear weapons, he stated, noting that it will also impose further penalties on the country.

Trump called the move long-overdue, noting that the terror designation is being used as part of the United States’ “maximum pressure campaign” against the hermit nation.

“Today, the United States is designating North Korea as a state sponsor of terrorism. Should have happened a long time ago. Should have happened years ago,” Trump said.

Trump’s announcement comes days after his return from a five-nation tour of Asia, which focused on putting a stop to North Korea’s menacing nuclear program. White House officials telegraphed the move before Trump’s departure.

According to U.S. officials, the murder of North Korean leader Kim Jong Un’s estranged half-brother in a Malaysian airport this year was an act of terrorism.

Other countries on the list of state sponsors of terrorism include Iran, Sudan, and Syria.
