Heading for the Fourth Nuclear Age

The roots of the nuclear order's unraveling can be traced to four distinct factors that have evolved over the last six decades: weaknesses in the original NPT formula, changes in the global distribution of power, nuclear weapons technology proliferation, and complacency with the current regime.

In a new Proliferation Paper published by the Institut Français des Relations Internationales' (Ifri) Security Studies Center, Ariel E. Levite examines the evolution of the global nuclear order since the advent of nuclear weapons in 1945 to present by breaking down the sixty-plus years of nuclear history into three analytically distinct "ages," each lasting roughly twenty years. By doing so, Levite traces back the roots of the current nuclear predicament to some early seeds of trouble which have gradually grown more profound. He attributes much of the unraveling of the nuclear order to:

  1. Certain inherent weaknesses in the original NPT formula;
     
  2. Changes in the global distribution of power since the codification of the nuclear order in the 1960s;
     
  3. The dissemination of nuclear weapon technology; and
     
  4. Complacency and subsequent disillusionment with the nuclear order since the early 1990s.

The paper further analyzes what could precipitate a new nuclear age around 2010. Levite argues that such a "fourth nuclear age" would likely be characterized by either a nuclear anarchy, which he believes has become the default option, or a more benign nuclear order manifested by lower numbers of weapons and stringent controls and restrictions on remaining nuclear arsenals and activities. He concludes by considering the more pressing requirements for regaining nuclear stability.

    What Does Nuclear Proliferation in East Asia Mean for Russia?

    Troubled by the growing salience of nuclear debates in East Asia, Moscow has responded in its usual way: with condemnation and threats. But by exacerbating insecurity, Russia is forcing South Korea and Japan to consider radical security options.

    Lukashenko’s Bromance With Trump Has a Sell-By Date

    Lukashenko is willing to make big sacrifices for an invitation to Mar-a-Lago or the White House. He also knows that the clock is ticking: he must squeeze as much out of the Trump administration as he can before congressional elections in November leave Trump hamstrung or distracted.
