Tensions between major powers continue to surface in international news today, creating a significant impact around the world. One of the main issues that attracts attention is the relationship between the United States and China. Unabated economic competition has resulted in a series of tariff policies and countermeasures that are disrupting global markets. Both countries are seeking to dominate advanced technology, with a focus on artificial intelligence and 5G, sparking fears of a new technological arms race. In Europe, tensions between Russia and NATO member countries are also increasing. Russia’s invasion of Ukraine remains a hot topic, with international sanctions imposed on Moscow. NATO is seeking to strengthen its defensive position in Eastern Europe, adding to Russia’s concerns about the alliance’s expansion. This situation causes geopolitical uncertainty, threatening regional stability. In Asia, the conflict in the South China Sea shows tensions between China and ASEAN countries. China claims almost the entire area, despite conflicting claims from countries such as Vietnam, the Philippines and Malaysia. Coast guard vessel incidents occur frequently, increasing the risk of military confrontation. The United States’ commitment to supporting small states in the region adds another dimension to the conflict. In the Middle East, tensions between Iran and Western countries, especially the US, are heating up again. After talks over the 2015 nuclear deal broke down, relations deteriorated further. Iran is intensifying its nuclear program, creating fears of a potential nuclear weapon and creating broader regional tensions, especially with US allies such as Saudi Arabia and Israel. In the context of climate change, collaboration and contention are also in the spotlight. The COP conference faces challenges in achieving consensus between major countries with differing economic and environmental interests. Although there are agreements to reduce carbon emissions, implementation is often hampered by national political and economic interests. Tensions are also visible in cyber security, with major powers accusing each other of hacking and digital espionage. Attacks on critical infrastructure have increased the need for tighter security and international cooperation, although political realities often hinder such collaboration. With these factors, tensions between major powers create complex dynamics that affect global stability. Today’s international news highlights how domestic policies, global ambitions and geopolitical confrontations are intertwined, creating new challenges for the world. An era where diplomacy and dialogue are becoming increasingly important to create long-term security in the face of existing threats.
