On August 7, 1998, al-Qaeda bombed the US embassies in East Africa, killing 224 people, including 12 Americans. In retaliation, a barrage of cruise missiles launched by the US military devastated an al-Qaeda base in Khost, Afghanistan. The network's capacity was unharmed. In late 1999 and 2000, Al-Qaeda planned attacks to coincide with the millennium, masterminded by Abu Zubaydah and involving Abu Qatada, which would include the bombing of Christian holy sites in Jordan, the bombing of Los Angeles International Airport by Ahmed Ressam, and the bombing of the USS The Sullivans (DDG-68).
On October 12, 2000, al-Qaeda militants in Yemen bombed the missile destroyer USS Cole in a suicide attack, killing 17 US servicemen and damaging the vessel while it lay offshore. Inspired by the success of such a brazen attack, al-Qaeda's command core began to prepare for an attack on the US itself.
