The United States government maintains a formal list of countries designated as 'State Sponsors of Terrorism,' a classification that triggers significant economic and diplomatic sanctions. Following the recent removal of Syria from this list, the designation now applies to only three nations: Cuba, Iran, and North Korea.

Placement on this list is determined by the US Department of State, which assesses whether a government has repeatedly provided support for acts of international terrorism. The consequences for listed countries are severe, including restrictions on US foreign assistance, a ban on defense exports and sales, and various financial controls that limit the ability of these nations to engage in international commerce.

While the removal of a country from the list is often the result of diplomatic negotiations or changes in a nation's foreign policy, the criteria for remaining on the list are strictly defined by US statute. The State Department periodically reviews these designations, though the process is often subject to intense political scrutiny. The current list reflects the US government's ongoing assessment of global security threats and its use of economic leverage to influence the behavior of foreign regimes.
