Intensified competition and distrust among the great powers—manifested in regional wars and a stalled arms control environment—have increased the possibility of renewed nuclear testing. There are indications that China, Russia, or the US might resume yield-producing tests of nuclear weapons—or have already done so—despite the collective self-imposed moratorium on such tests.
The US, in coordination with Israel, has launched a major military operation against Iran, striking multiple targets across the country. President Trump on Saturday evening announced that Iran’s Supreme Leader, Ayatollah Ali Khamenei, had been killed in the course of the operation — a claim formally confirmed by Iranian authorities on Sunday morning.
Assad’s departure has altered Syria’s leadership landscape, but it has not translated into coherent state reconstitution. Political fragmentation has become structurally embedded in the post-Assad political order. Syria is not undergoing a conventional political transition. Rather, it is consolidating into a post-regime, pre-state environment.
The Supreme Court’s landmark ruling striking down President Trump’s tariffs goes beyond dismantling a central pillar of the administration’s trade policy. It also significantly constrains the executive branch’s ability to impose tariffs unilaterally, shifts authority in tariff decision-making back to Congress and alters the strategic calculus of U.S. economic statecraft.
The deployment of a second U.S. aircraft carrier strike group to the Middle East marks a strategic inflection point in the unfolding U.S.–Iran confrontation. The buildup now includes destroyers, additional strike aircraft and reinforced air defenses. While it does not make war inevitable, the buildup significantly widens the spectrum of escalation pathways.
Since assuming office in January 2025, President Donald Trump has attempted to fulfill his campaign promise to end the Russia–Ukraine war. While the administration has made significant progress toward a settlement, negotiations remain stalled over the Donbas region and the Russian-occupied Zaporizhzhia nuclear power plant.
The world just witnessed another high-intensity, live-fire Chinese military exercise around Taiwan. The dispute over the island represents one of the most serious risks of another great-power war. Even if unsuccessful, a Chinese attack against Taiwan would risk nuclear escalation, global economic shock, and long-term degradation of international relations.
The Ukrainian political and military system stands at a critical juncture, as rival factions risk deepening internal divisions. Recent developments suggest that President Zelensky’s appointment of former military intelligence chief Kyrylo Budanov as chief of staff was not merely an administrative change. It marked the beginning of a subtle but consequential redistribution of power.
NATO’s role in the Arctic has undergone a dramatic transformation, shifting from a Norwegian policy of “High North, Low Tension”—designed to promote regional stability and cooperation with Russia after the Cold War—to one of strategic necessity. Yet NATO’s expanding political commitments have outpaced its actual capacity to sustain forces in extreme latitudes.
South Korean defense systems have reshaped NATO’s arms policies and procurement processes as the country transformed from a niche supplier into a competitive player in the global arms market. With growing security challenges in Europe, several European countries are turning to Seoul as a viable option to accelerate their weapons programs.
