South Korean President Lee Jae-myung, a month into his presidency, emphasizes the need for "pragmatic diplomacy" to maintain the US-Japan-South Korea alliance while improving ties with China and Russia. However, recent developments suggest that achieving this goal is becoming increasingly challenging.

Initially, China sent an invitation to Lee’s government for the military parade on September 3, while US Secretary of State Rubio canceled his visit to South Korea. Furthermore, the inability to reach agreement on tariffs and military expenses with the United States complicates matters. Additionally, frequent military activities by Beijing in the Yellow Sea have added pressure on Lee's government to find a balance between national security and international relations.

Meanwhile, President Trump recently stated at a NATO summit that he would consider providing Ukraine with more "Patriot missile defense systems." However, shortly thereafter, the US Department of Defense announced it would suspend weapons deliveries to Ukraine, creating confusion. For Ukraine, missile defense systems are crucial as a first line of defense against increasing attacks, particularly from drones launched by Russia.

Dr. Shen Ming-shih argues that despite China’s aircraft carriers nearing the second island chain, China is still significantly behind the US military in terms of long-range operational capabilities and power systems. Operating near the first island chain exposes them to US military strikes. Discussing Taiwan's defense strategy, Dr. Shen suggests that as long as Taiwan maintains its resolve and commitment, along with quick support from US and Japanese allies, it can deter a Chinese invasion. Moreover, the significance of Trump's bombing of Iranian facilities reflects two key aspects: his commitment to action and a shift in the US strategic focus to the Indo-Pacific region.
