Blindspot

Right coverage gave less weight to that same South Korean moratorium demand and appeal for Chinese mediation, a key diplomatic angle in the Center summary.

History

Historical Context

START I, signed 31 July 1991 by the United States and the Soviet Union, capped deployed warheads at 6,000 and ICBMs at 1,600, a limit that fell to 1,550 warheads under New START in 2011. After the 2001 Bush-Putin SORT cut U.S. warheads to about 2,200, Russia’s 2023 suspension of New START revives fears as North Korea builds enrichment capacity and China expands its arsenal.
