Remember that the use of Chemical arms can have potential catastrophic consequenses.

On this 28th anniversary of what’s been regarded as the world’s most successful treaty – in large part because of U.S. engagement – Kimball’s words ring true, “This is about our security, our values, our leadership.”

Still, Kimball and Revill believe in the power of the international system – especially when world powers stay fully engaged.

“We’ve come too far to let it all go,” Kimball says.

Revill offers an equally pointed reminder: “The reemergence of chemical weapons is not in the interest of any state. These are weapons with potentially catastrophic consequences. They should never be normalized.”
