Over the last five decades, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) has served as the bedrock for keeping the world safe from a nuclear doomsday. Now it stands on the brink of a breakdown.

The new government of Korea is off to a hectic start with multilateral diplomacy. Last month, President Yoon Suk-yeol made a diplomatic debut at the NATO (North Atlantic Treaty Organization) Summit alongside the leaders of 30 member states, and for the first time, three other Asia-Pacific partners, Japan, Australia, and New Zealand.

Liberal democracy, along with the open market economy, has been the main engine of progress for humanity over the last century.

The summit between U.S. President Joe Biden and his Korean counterpart Yoon Suk-yeol took place merely a dozen days following President Yoon's inauguration.

I convey my heartfelt congratulations to you on taking the helm of Team Korea for the next five years. I empathize with you for the enormity of the responsibility that you said you felt for the future of the Korean people upon winning the election, which must have been a sleepless night for you and many Koreans.

The world stands at a tipping point. The ongoing Russian invasion of Ukraine is a vivid reminder of rising insecurity in global geopolitics. The post-World War II global order led by the United States shows signs of fatigue, increasingly unable to meet the mounting challenges from both competitors and rogue players.

The Russian invasion of Ukraine is an outright affront to the international norm of non-aggression. It is wreaking humanitarian havoc on a scale never seen in Europe since the end of World War II.

This year marks the 50th anniversary of former US president Richard Nixon's visit to China. The visit was a dramatic turning point in world politics and the beginning of a new chapter in the US-China relationship.

The 2022 South Korean presidential election is around the corner, with less than a month to go. Korea watchers around the world are anxiously awaiting its outcome, with many apprehensive of the potential fallouts on South Korea's relations with neighboring countries. 

The new year has started with the COVID-19 pandemic still hanging over our heads. On top of that, clouds of hyper-uncertainty are gathering over the global security horizon.

The order among the nations, or more realistically the balance of power among major powers is undergoing tectonic shifts. At its heart lies the fast rise of China relative to the United States.

The overdue summit between the two leaders of the two most powerful states, the United States and China, finally took place, though virtually.

Volatility in the strategic equation of the Korean Peninsula has recently risen. From a short-term perspective, the volatility largely stems from the growing anxiety over a prolonged stalemate in North Korea's dialogue with the United States.

The Tokyo 2020 Olympics and Paralympics were finally held during this past summer. Under the cloud cast by the COVID-19 pandemic, there was uncertainty until the last minute. Eventually the decision was taken to proceed with the Games but without spectators, something that was unprecedented.

Afghanistan fell again into the hands of the Taliban, "the day after" the withdrawal of the United States troops began in a manner so abrupt and fast. The speed of the government collapse and ensuing shocks betrayed not only popular expectations of the outside world but also the analysis by the U.S. intelligence community.

Last week South and North Korea resumed operation of cross-border hot lines. The move came as a pleasant surprise after the North unilaterally severed them over a year ago.

The allied powers victorious in World War II, led by the United States, created the United Nations as a universal institution with three objectives: stable peace, sustainable development and universal human rights.

The recent summit between the Republic of Korea (ROK) and the United States produced a communique, akin to the thrilling moment when BTS, one of the world's most idolized pop groups from Korea, grabbed multiple Grammy awards.

April 22 marked the 51st Earth Day, and on that day United States President Joseph Biden hosted his first summit on climate change in line with this year's theme, "Restore Our Earth." This reflects the mounting concern over the global unsustainability crisis facing humanity.

The human race is facing the biggest threat of an unprecedented self-destructive force created by people. Since last year, a group of world-renowned scientists called the Bulletin of the Atomic Scientists has set the doomsday clock at only 100 seconds to midnight, which denotes the biblical moment of self-destruction.
