For our present conflict, Vladimir Putin is not alone at fault. His actions have often been reactions to America’s unilateral moves.

Putin responded with his military buildup in the Baltic. George W. Bush abrogated the Anti-Ballistic Missile Treaty that Richard Nixon had negotiated, Putin responded with a buildup of the offensive missiles he put on display last week.
