H.Res. 1099: Reaffirming Iran remains the largest state sponsor of terrorism.

H. Res. 1099 is a statement-of-position measure, not a bill that directly changes sanctions, spending, or criminal law. Its core purpose is simple: the House formally declares that Iran continues to be the largest state sponsor of terrorism. The text ties that conclusion to Iran's support for Hezbollah, Hamas, the Houthis, and other proxy groups, as well as to attacks that have killed Americans.

The resolution builds its case by listing a series of allegations and findings. It points to Pentagon estimates that Iranian-backed militias were responsible for the deaths of at least 603 U.S. service members in Iraq. It also references the January 2024 attack on Tower 22 in Jordan that killed three U.S. soldiers, describing it as an Iranian-backed proxy attack. The measure further accuses Tehran of backing assassination plots on U.S. soil and harboring senior al-Qaeda figures.

It also connects terrorism concerns to Iran's nuclear program. The text says Iran's refusal to abandon its nuclear and missile activities led to the reimposition of six U.N. Security Council resolutions in September 2025, and it cites IAEA Director General Rafael Grossi's concerns about Iran's uranium stockpile and lack of access to undeclared sites. That linkage matters because Congress is framing Iran not just as a regional proxy threat, but as a broader strategic danger.

In practical terms, the resolution is mostly about messaging, oversight, and political positioning. It can strengthen the case for future sanctions, military deterrence, diplomatic isolation, or tighter enforcement of existing Iran policy. It also puts members of Congress on the record, which can shape debate over Middle East policy, U.S. force protection, and any future negotiations with Tehran.
