Washington: U.S. Defense Secretary Pete Hegseth highlighted the importance of fortifying U.S. and Japanese military forces through "realistic" training across the first island chain in Japan, a strategic Pacific defense line essential for countering China's expanding naval influence.

According to Yonhap News Agency, Hegseth's comments came during a meeting with Japanese Defense Minister Shinjiro Koizumi at the Pentagon, amidst ongoing tensions between China and Japan. The tensions were exacerbated by Japanese Prime Minister Sanae Takaichi's statements regarding Taiwan in November, which prompted Beijing to issue travel advisories and apply economic pressure on Tokyo.

The meeting with Koizumi followed a joint physical training session between Hegseth and the Japanese Defense Minister, which Hegseth described as a demonstration of the "actual physical strength of the U.S.-Japan alliance." Hegseth emphasized the necessity for "hard-nosed realism" and a "practical, common-sense approach" to unite the vital national interests of both countries and maintain peace.

Hegseth specifically noted the importance of conducting realistic training exercises in Japan and across the first island chain as a way to showcase operational readiness and ensure peace through strength. The first island chain, which spans from Japan through Taiwan to the Philippines, is considered a crucial defense perimeter for maintaining America's regional dominance in the face of China's increasing assertiveness.

The White House's recent National Security Strategy underlined the need for South Korea and Japan to enhance their capabilities to defend the first island chain, while also asserting that the U.S. military must be prepared to deny aggression "anywhere" along the chain.

During the discussions, Koizumi remarked on the strengthening bilateral alliance, highlighting the "extremely close" communication between President Donald Trump and Prime Minister Takaichi, and the strong relationship between the defense leaders. Reflecting on the morning's physical training session, Koizumi noted his slight dehydration, which was promptly addressed by U.S. medical personnel, and remarked on the tangible sense of alliance support he felt.

The talks were anticipated to cover a range of bilateral security issues, including U.S. calls for Japan to increase defense spending and joint measures to enhance deterrence against Chinese threats.
