After the Cold War, the UN saw a radical expansion in its peacekeeping duties, taking on more missions in ten years than it had in its previous four decades. Between 1988 and 2000, the number of adopted Security Council resolutions more than doubled, and the peacekeeping budget increased more than tenfold. The UN negotiated an end to the Salvadoran Civil War, launched a successful peacekeeping mission in Namibia, and oversaw democratic elections in post-apartheid South Africa and post-Khmer Rouge Cambodia. In 1991, the Security Council demonstrated its renewed vigor by condemning the Iraqi invasion of Kuwait on the same day of the attack, and later authorizing a US-led coalition that successfully repulsed the Iraqis. Undersecretary-General Brian Urquhart later described the hopes raised by these successes as a "false renaissance" for the organization, given the more troubled missions that followed.
