Korean Peninsula -Etfa

The security situation between North and South Korea remains tense after North Korea sent five drones across South Korean territory on 26 December 2022. South Korea immediately reacted to the incursion and scrambled its fighter aircraft and attack helicopters to shoot down them down. The situation resulted in increased military presence and heightened surveillance along the border and highlights the ongoing tensions and mistrust between the two nations. Ironically, this was just one in a chain of events happening in the Korean Peninsula, among others.

More recently, South Korea’s President Yoon Suk Yeol expressed his country’s interest in developing nuclear weapons or asking the United States to consider redeploying them in the region. Though he clarified that the country had no active nuclear weapons development programme, such a statement could complicate the regional security environment and spark an arms race in the Peninsula.

The situation remains a major source of global concern and ongoing diplomatic efforts are not producing any fruitful results to find a peaceful resolution. One reason for this could be that the situation is not as simple as it appears to be. There are intricate bilateral and multilateral relationships inside and outside the Korean Peninsula with key players being North Korea, South Korea, Japan, the US, and China. In order to understand the current situation and foresee the future, one must understand the bilateral and multilateral engagements at all levels between these states.

Regarding the US and South Korea, the US Secretary of Defense Lloyd Austin visited South Korea in late January to reassure its ally that any attack on ‘one of us’ would be considered an attack on the entire US alliance and the country would be provided NATO-style security against the North Korean threat. The proposition to increase joint military exercises and cooperation with Japan – another key player and US ally in the region – was also considered.

Japan’s role has become immensely important after the ongoing security situation in the Korean Peninsula. Earlier in December 2022, Japan announced its National Defense Strategy. The policy calls for Japan to play a proactive role in regional and global security, including providing military support to its allies and engaging in collective self-defence, investing in research and development, increasing defense production and the technological base of the country. This has been seen as a response to the growing threat posed by North Korea’s nuclear weapons and ballistic missiles as well as China’s increasing military presence.

Tensions with North Korea and China have significantly improved relations between the US, Japan and South Korea. Late last year, the countries reaffirmed their trilateral partnership in security and other areas. Though there may be challenges with respect to Japan and South Korea given their historical differences, the agreement in important in light of US’ Indo-Pacific Strategy.

Similarly, there is a dimension to the North Korea-China relationship as well that needs to be considered while assessing the entire situation. Both countries were old allies. However, China voted against North Korea in 2006 following its nuclear tests. In 2019, China revived its relations with North Korea and Chinese President Xi Jinping paid a historic visit to the country and called their relationship ‘unshakable’. At the same time, China has also been unsuccessfully trying to woo South Korea to push Seoul away from Washington.

Last but not least, we have US-China relations with North Korea considered to be a potential area of cooperation between the two global powers regarding denuclearisation and promoting stability.

Given high-stakes for the two global powers – US and China – and their corresponding relations with regional players, the Korean Peninsula matrix remains ever more complex. With rising competition and mistrust between regional states, there is a need to promote security cooperation and diplomacy through negotiations and dialogue, otherwise, there is high risk of a major conflict in Northeast Asia due to increasing nuclear and missile developments by North Korea.

The US-Israel War on Iran: Objectives, Strategy, and Escalation Management

Zahra Niazi
‘States tend to overestimate themselves or the benefits and swiftness of war, and to underestimate their opponents’ capabilities, intentions, or the costs and duration of war.’ If anything, the 2026 war initiated by the United States and Israel against Iran shall be remembered in the annals of warfare among the most visible manifestations of this dynamic.
The war, immediately preceded by the January mass protests in Iran, did not represent a sudden rupture but rather the continuation of a 47-year-long confrontation and a more intense phase of the June 2025 war.
The US Secretary of War, Pete Hegseth, defined the war’s objectives as being laser-focused: to destroy Iran’s missile capabilities and its security infrastructure, while ensuring that it could never develop nuclear weapons. Beyond these stated objectives, among the priorities on the continuum also lay the objective of regime change, with both President Trump and Prime Minister Netanyahu explicitly calling on the Iranian population to take over the government at the outset of the war.

Marka-e-Haq to the Peace Talks: Pakistan’s Middle Power Status

On 7th May 2025, Pakistan’s military forces took the international security community by surprise when it demonstrated operational superiority against its larger belligerent adversary India with its rapid and coordinated response. The Four-Day conflict proved to be a watershed moment for Pakistan, marking its rapid emergence as an important player in the region. In recent years, amidst the ongoing global competition between the United States and China, Islamabad has adopted a position of ’Strategic Balancing,’ where it maintains ties of cooperation with both Beijing and Washington. Deft diplomacy, emphasis on geo-economics, and credible conventional and strategic deterrence have remained the foundational pillars for Pakistan’s ambition as a rising middle power

Debunking the S-400 Shield: Lessons from the India-Pakistan Conflict

Air defense has always been a central aspect of warfare. In South Asia, the phenomenon carries immense significance due to compressed reaction times. In this context, one of the most-hyped systems is the Russian-made S-400, touted by New Delhi as a one-stop solution to counter aerial threats from both Pakistan and China.
The 2025 conflict between India and Pakistan marked an important chapter in testing the S-400 technology. The conflict began on May 7, when India attacked what it alleged were terrorist targets in both Pakistani-held Kashmir and Pakistan proper, using drone and missile strikes. The conflict lasted for four days, culminating in a U.S-facilitated ceasefire. However, the brief conflict debunked a lot of the myths regarding the S-400 technology.
First, India claimed that the mobile S-400 would be able to control Pakistan’s airspace. In contrast, Pakistani aircraft continued to operate freely, according to official briefings by the Pakistani military. Although the Pakistan Air Force (PAF) aircraft were in their own airspace, they were still within the air defense range.
