SEOUL, Feb. 9 (AP) — North Korean leader Kim Jong Un and his young daughter took center stage at a huge military parade, fueling speculation that she’s being primed as a future leader of the isolated country as her father showed off his latest, largest nuclear missiles.

Wednesday night’s parade in the capital, Pyongyang, featured the newest hardware in Kim’s growing nuclear arsenal, including what experts said was possibly a new solid-fuel intercontinental ballistic missile he may test in coming months.

That missile was part of around a dozen ICBMs Kim’s troops rolled out at the event, an unprecedented number that underscored how he continues to expand his military capabilities despite limited resources in face of deepening tensions with his neighbors and the United States.

The parade was the fifth known public appearance by Kim’s daughter, Kim Ju Ae, his second-born child who is believed to be around 10 years old. On Tuesday, Kim Jong Un brought his daughter to visit troops as he lauded the “irresistible might” of his nuclear-armed military.

State media have signaled a lofty role for Kim Ju Ae. She’s been called “respected” and “beloved,” and a photo released Tuesday showed her sitting in the seat of honor at a banquet, flanked by generals and her parents.

North Korean photos released Wednesday showed Kim, wearing a black coat and fedora, attending the parade with his wife and daughter. Kim smiled and raised his hand from a balcony as thousands of troops lined up in a brightly illuminated Kim Il Sung Square, which is named after his grandfather, the nation’s founder.

North Korea’s official Korean Central News Agency said all of the soldiers and spectators at the square raised “stormy cheers of ‘hurrah!’” and chanted the name of their ruler, a “great brilliant commander” who is “beefing up the military muscle with his outstanding military strategic ideas.”

The parade marked the 75th founding anniversary of North Korea’s army and came after weeks of preparations involving huge numbers of troops and civilians mobilized to glorify Kim’s rule and his relentless push to cement the North’s status as a nuclear power.
