In a speech earlier this month, senior National Security Council official Pranay Vaddi acknowledged a new, uncomfortable reality: For the first time ever, the United States must deter two nuclear peer adversaries. 

“The president recently issued updated nuclear weapons employment guidance, which takes into account the realities of a new nuclear era,” Vaddi told the Arms Control Association in a speech on June 7.
