As Putin threatens to strike Ukraine with tactical nuclear weapons and Biden warns that this risks escalation to nuclear Armageddon, many observers have wondered aloud whether the septuagenarian or the octogenarian or both have lost touch with reality. Pundits declare Putin’s threats “irrational,” since according to them no rational leader could order a nuclear strike on another state. Critics of Biden have seized on his references to nuclear annihilation, for example when he recently said that “for the first time since the Cuban Missile Crisis, we have a direct threat of the use of nuclear weapons” which “could end in Armageddon,” as decisive evidence of senility.
