An arms embargo is an embargo that applies to weaponry. It may also include "dual use" items. An arms embargo may serve one or more purposes:
US President Jimmy Carter implemented the embargo against the 1976 Military Junta due to the Dirty War. This was joined by the United Kingdom after the 1982 Falklands War. The ban was lifted in the 1990s when Argentina was named a Major non-NATO ally. During those years Argentine Armed Forces shifted to Western European countries and Israel for supplies.
The United States government imposed an arms embargo to Indonesia in 1999 due to human rights violations in East Timor. The embargo was subsequently lifted in 2005.
There have been international sanctions against Iran since 1979. In March 2007, UN Security Council Resolution 1747, imposed a ban on arms sales with Iran.
