In 1999, Australia led a United Nations force into East Timor to help establish democracy and independence for that nation, following political violence. During this period Australia committed to a number of other peacekeeping and stabilisation operations: notably in Bougainville, including Operation Bel Isi (1998–2003); as well as Operation Helpem Fren and the Australian-led Regional Assistance Mission to Solomon Islands (RAMSI) in the early 2000s; and the 2006 East Timorese crisis. Following the September 2001 terrorist attacks on the US and the subsequent War on Terror, Australia committed troops to the Afghanistan War and the Iraq War. These events, along with the 2002 Bali Bombings and other terrorist incidents, led to the creation of a National Security Committee and further anti-terrorist legislation.
