Japan and South Korea’s leaders announced they will not attend this week’s NATO Summit in The Hague due to U.S. airstrikes targeting Iranian nuclear facilities – an action reflecting growing complexity in international relations amid intensifying Middle Eastern tensions.
Japanese Prime Minister Shigeru Ishiba recently cancelled his scheduled attendance, citing “various circumstances,” according to the Foreign Ministry. Although no specific reasons were given, media speculated the decision might have been affected by a meeting between NATO and Indo-Pacific Four (IP4) nations and President Donald Trump as well as any prospect of bilateral meetings between either grouping.

South Korean President Lee Jae-myung also decided not to attend, citing national issues and uncertainty in the Middle East as motivators. Vice Industry Minister Moon Shin-hak also expressed her concerns over any negative economic effects resulting from U.S. airstrikes targeting Iran’s nuclear facilities. worldview.stratfor.com +5 newrepublic.com +5 And Asianews Network offers its coverage as follows.
At the NATO summit, their absence underscores the delicate balance that nations are striving to strike amid changing geopolitical dynamics. Both Japan and South Korea had long been close allies of the U.S.; however, its recent unilateral military actions have caused both nations to reevaluate diplomatic ties.

Australia, another member of the IP4, announced on Sunday that Prime Minister Anthony Albanese will not attend the G7 summit, with Deputy Prime Minister Richard Marles instead representing Australia at this year’s gathering. Albanese justified his decision by noting that many other IP4 leaders also wouldn’t attend, while also affirming a future meeting between Trump and himself is scheduled – sources include Reddit.com (+3), Reuter’s (+1), AsiaNews.network (1+) and The Australian (+1).

The NATO summit, originally meant to highlight unity and increase defense spending, has been overshadowed by the U.S.-led military strike against Iran. European leaders who were left out of discussions now face pressing questions regarding U.S. unilateralism and potential risks of wider conflict.
As this summit proceeds without key Indo-Pacific leaders present, the international community closely watches to see how events may shape future diplomatic and security collaborations.
