The current global disarray is often misdiagnosed. The system truly at risk is the deeper, 80-year-old framework created post-WWII to prevent great power war. This is a more profound rupture than the fraying of the 30-year-old, US-led post-Cold War order.

The current era of multipolarity, global economic integration, and tensions between rising and incumbent powers (like China and the US) is more analogous to the early 20th century before WWI than the bipolar Cold War. This historical parallel carries stark warnings about the potential for conflict.

The greatest risk of nuclear weapon use is not a peacetime accident but a nation facing catastrophic defeat in a conventional war. The pressure to escalate becomes immense when a country's conventional forces are being eradicated, as it may see nuclear use as its only path to survival.

The modern system of nearly 200 sovereign states wasn't a historical accident. For newly independent nations after colonialism, joining the UN provided a crucial framework of sovereignty that prevented international anarchy and allowed them to focus on internal nation-building.

In global conflicts, a nation's power dictates its actions and outcomes, not moral righteousness. History shows powerful nations, like the U.S. using nuclear weapons, operate beyond conventional moral constraints, making an understanding of power dynamics more critical than moralizing.

The proximity to WWII created a powerful sense of restraint among world leaders in the 1960s. Today, that lived memory is gone. The absence of a deep, culturally ingrained fear of total war has eroded the political will for peace, making the world more dangerous.

Nuclear deterrence works because the weapons provide a "crystal ball effect." Unlike WWI leaders who couldn't foresee 1918's carnage, modern leaders have a stark, pessimistic view of a nuclear war's outcome. This shared vision of guaranteed calamity creates enormous incentives to avoid starting such a conflict.

We are living in a historically abnormal period of peace defined by three numbers: 80 years without a great power war, 80 years without nuclear weapon use, and only 9 nuclear states. This fragile peace, the longest since Roman times, is not a natural state and is constantly eroding, requiring active work to sustain.

After the Cold War, the UN was retooled to manage internal conflicts and deploy peacekeepers. This shift, driven by a unipolar moment with fewer state-vs-state wars, meant it moved away from its classic role as a high-level mediator, leaving it unprepared for today's resurgence of interstate conflict.
