Política nuclear americana durante a guerra na Ucrânia

The United States and Russia, whose agenda is dominated by strategic matters, possess more than 90% of the world’s nuclear weapons. Efforts to reduce their number and salience in American nuclear strategy have been affected by domestic resistance and international developments. Currently, Moscow’s pattern of disrespect for arms control agreements, in a context of war in Ukraine, and of repeated Russian nuclear threats, is joined by an American perception of a massive expansion of Chinese nuclear forces. Those events serve as an impetus for American nuclear modernization and make dialogue to limit the world’s two largest nuclear arsenals more difficult.
