In November 2008, the Iraqi Parliament approved two major agreements with the US administration:

1. US-Iraq Status of Force Agreement (SOFA) – A legally binding agreement which defines temporary presence and activities of US military personnel, crucial protection and operational powers, and the eventual date for a US troop withdrawal from Iraq.

2. US-Iraq Strategic Framework Agreement (SFA) – A broader agreement for long-term bilateral cooperation between the two countries in areas including political, diplomatic, defense, security, economic, energy, and law enforcement.

The first of these agreements was enforced for three years. Under its terms, US troops withdrew from Iraq by the end of 2011. The second agreement stipulates that either party to the US-Iraq SFA shall terminate or amend terms of the agreement following certain legal and constitutional measures.

According to Section 11 of the SFA, any party to the SFA with an intention to terminate the agreement must provide written notice to the other party, and the termination shall be effective one year after the date of such a notification. Furthermore, the terms of the SFA may be amended with the mutual written agreement of the parties and according to the constitutional procedures in effect in both countries.

Looking into this.

Was the first agreement annulled when it expired or when troops returned?!
