North Korea has escalated its criticism of Japan's military expansion and its security cooperation with the United States and South Korea, asserting that these actions threaten regional stability. This heightened rhetoric, appearing in over a dozen state media reports since early July, has coincided with an unusual silence from Pyongyang regarding its own recent missile launches, prompting questions about its strategic messaging.
Pyongyang's statements have specifically targeted Japan's acquisition of counter-strike capabilities, its testing of U.S.-made Tomahawk cruise missiles, increased defense spending, and its annual defense white paper. Kim Yo Jong, sister of leader Kim Jong Un, warned of "additional military options" in response to Japan's transformation into a military power. A commentary from the Korean Central News Agency (KCNA) described Japan's 2026 defense white paper as a "re-invasion-minded" document justifying military expansion.
North Korea also criticized the annual U.S.-South Korean Ulchi Freedom Shield military drills, accusing the trilateral cooperation of evolving into a "nuclear alliance." Washington and Seoul maintain the drills are defensive. Another KCNA commentary accused the U.S. of pursuing a strategy that lowers the threshold for nuclear weapons use, citing extended deterrence commitments to South Korea and Japan.
Japan, in 2022, announced plans to double defense spending to 2% of GDP to counter threats from China, Russia, and North Korea, including investments in long-range missiles. Analysts suggest North Korea's primary goal is to frame Northeast Asia as a contest between rival blocs: the U.S.-South Korea-Japan alliance against North Korea-China-Russia. This strategy aims to bolster support from Beijing and Moscow, cement its escape from diplomatic isolation, and justify its nuclear arsenal.
The heightened rhetoric has occurred alongside an uncharacteristic silence from North Korean state media regarding recent ballistic missile tests. Analysts speculate these tests may involve upgrades to existing systems rather than new weapons, or are linked to prospective military exports, potentially with Russian technical assistance. Ukrainian President Volodymyr Zelenskiy has repeatedly stated that Russia uses North Korean missiles against Ukraine.
