A veto by one permanent member is enough to sink a resolution. On February 4, two veto-wielders, Russia and China, banded together to vote against a resolution that provided for Syria’s president, Bashar al-Assad, to step aside, halt a ruthless crackdown on dissidents, and begin a transition to democracy. Assad saw the veto as a green light to crack down even harder. A week before the vetoes, the U.N. estimated the death toll at 5,400. On February 28, it was revised to more than 7,500, the result of a merciless artillery and tank bombardment of the central city of Homs, an opposition stronghold.
