forces complete the 2011 withdrawal from Iraq (2011-12-18).
Context
The 2008 SOFA sat as parent. Neighbouring Afghan surge is a different theatre. He did not sit as Maliki. A remaining vacuum is stored as mixed context, not as unique ISIS authorship.
Libya 19 March 2011 is a neighbour force file. Afghan residual 2016 is a later different theatre.
A United States president proposes, signs, vetoes, and directs the executive. Congress enacts statutes. The Federal Reserve, states, courts, and later presidents share later series. Office-holding is not authorship of every later outcome. Allegation is not a completed judgment. Legislative achievements require shared congressional attribution. He does not set the federal funds rate, write a state Medicaid waiver by himself, or convert a 2009 oath into a unique 2016 uninsured coefficient. A signature is not unique authorship of a House and Senate text. A troop order is not authorship of every later round. He is not president as of 27 August 2026. Donald Trump is president from 20 January 2025. Joe Biden was president 2021–2025.
Why it matters
The path is humanitarian access: a completed end of a U.S. combat presence with a later-security caveat stored as mixed context.

Evidence
The sources behind this fact and its verification state.

- 2.White House archives — 14 December 2011 remarks on the end of the war in IraqWhite House (archives) · High credibility · verified
What the sources establish
White House (archives) carries the official instrument or communique. BBC records the same dated act independently.
Established: 18 December 2011 last-troop exit, independently reported.
Not established: that ISIS uniquely sat because of that Sunday, or a unique later Iraqi civilian-death coefficient from the ceremony.
The 2008 SOFA set the date. Iraqi authorities received sovereignty. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies U.S. forces complete the 2011 withdrawal from Iraq, not a later speech about U.S. forces complete the 2011 withdrawal from Iraq.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He completed the withdrawal. The 2008 SOFA set the date. Iraqi authorities received sovereignty. That limit is the alternative to treating office-holding as authorship of every later series.
