Repeated US Vetoes of UN Security Council Gaza Ceasefire Resolutions

What Happened

In 2025, the United States vetoed at least two UN Security Council resolutions demanding an immediate ceasefire in Gaza, bringing the total US vetoes on Gaza ceasefires to six. In each case, the US was the sole dissenting vote — all other 14 members of the Security Council voted in favor.

June 2025 Veto

The draft resolution called for "an immediate, unconditional and permanent ceasefire in Gaza." It received 14 votes in favor from all ten elected members and four of the five permanent members. The United States was the sole veto.

September 2025 Veto

The US vetoed another ceasefire resolution at the Security Council's historic 10,000th meeting, where famine and the possibility of genocide in Gaza were discussed. Amnesty International called the veto "a greenlight for Israel's campaign of annihilation in Gaza."

US Representative Dorothy Shea called the resolutions "unacceptable," stating the US would not support any measure that fails to condemn Hamas and does not call for Hamas to disarm and leave Gaza.

Legal Analysis

1. Geneva Conventions Common Article 1: The US has an obligation to "ensure respect" for the conventions — blocking ceasefire resolutions while violations are documented is inconsistent with this obligation.
2. Genocide Convention Article 1: The obligation to prevent genocide requires affirmative action; blocking ceasefire resolutions while genocide allegations are under investigation may constitute failure to prevent.
3. UN Charter Article 24: Security Council members bear "primary responsibility for the maintenance of international peace and security" — serial vetoes blocking peace measures undermine this responsibility.
4. ICJ proceedings: The vetoes occurred while the ICJ had ongoing proceedings related to the conflict, and while the ICC had issued arrest warrants.

Why This Is Classified Severe

• Sole dissenter: The US was the only country blocking consensus ceasefire demands.
• Enabling role: Each veto enabled continued military operations with documented civilian casualties.
• Genocide context: The September veto occurred during a meeting where genocide was being discussed.
• Pattern: Six total vetoes demonstrates a systematic policy of enabling, not an isolated decision.
