North Korea opposes war but would use nuclear weapons if South Korea attacked, Kim Yo Jong, the powerful sister of leader Kim Jong Un, said on Tuesday, in a warning that analysts said is probably aimed at the South’s incoming conservative president.

Kim Yo Jong, a senior official in the government and the ruling party, said it was a “very big mistake” for South Korea’s minister of defense to make recent remarks discussing attacks on the North, state news agency KCNA reported.

South Korean Defence Minister Suh Wook had said on Friday that his country’s military has a variety of missiles with significantly improved range, accuracy, and power, with “the ability to accurately and quickly hit any target in North Korea.”

Both Koreas have increased displays of military strength after North Korea test-fired a range of increasingly powerful missiles this year. Officials in Seoul and Washington also fear it may be preparing to resume testing nuclear weapons for the first time since 2017 amid stalled negotiations.

In another statement directed toward Suh on Sunday, Kim Yo Jong called him a “scum-like guy” and warned that the South may face a “serious threat” because of his comments.

Her statements come amid tensions over North Korea’s accelerating weapons tests this year, including its first test of an intercontinental ballistic missile since 2017 on March 24, as her brother revives nuclear brinkmanship aimed at pressuring Washington to accept the North as a nuclear power and remove crippling sanctions.

Some experts say the North may up the ante in the coming months, possibly test-flying missiles over Japan or resuming nuclear explosive tests, as it tries to get a response from the Biden administration, which is distracted by Russia’s invasion of Ukraine and an intensifying rivalry with China.

The renewed tensions have been a major setback for outgoing South Korean President Moon Jae-in, a dovish liberal who had staked his presidential term on his ambitions for inter-Korean rapprochement.

During a visit to the country’s strategic missile command last week, Suh said South Korea has the ability and readiness to launch precision strikes on North Korea if it detects the North intends to fire missiles at South Korea.
