The fabric of arms control has been fraying, notably with the abandonment in 2019 — first by Washington, then by Moscow — of the Intermediate-Range Nuclear Forces Treaty.
Schultz was the longest serving secretary of state since World War II and had been the oldest surviving former Cabinet member of any administration. The former Marine Corps artillery officer was 100.
The treaty limits each country to no more than 1,550 deployed nuclear warheads and 700 deployed missiles and bombers, and envisages sweeping on-site inspections to verify compliance.
With the official withdrawal from the treaty, which allowed the U.S. and Russia overflight rights to inspect military facilities, only one arms-control pact is still in force between the former Cold War foes.
