Fact Check: Senator Sanders Warns Against U.S. Involvement in Netanyahu's War Against Iran
What We Know
On June 16, 2025, Senator Bernie Sanders (I-Vt.) issued a statement expressing strong opposition to U.S. involvement in military actions initiated by Israeli Prime Minister Benjamin Netanyahu against Iran. Sanders characterized Netanyahu's actions as illegal and warned that they could lead the U.S. into another military conflict without Congressional authorization. He emphasized that the U.S. Constitution mandates that only Congress has the authority to declare war, stating, "Whatever you think of the corrupt and authoritarian Iranian regime, this attack clearly violates international law and the United Nations Charter" (source-1).
Additionally, Sanders introduced the "No War Against Iran Act," which aims to prohibit the use of federal funds for military action against Iran without explicit Congressional approval (source-2). This legislative move reinforces his position that the U.S. should not be involved in what he describes as Netanyahu's "war of choice" (source-2).
Analysis
Senator Sanders' statements and legislative actions reflect a consistent stance against U.S. military involvement in conflicts initiated by foreign governments without Congressional oversight. His assertion that Netanyahu's military actions against Iran are illegal aligns with international law principles, which generally require a clear justification for military action, especially when it involves another sovereign nation (source-1).
The introduction of the "No War Against Iran Act" is a significant legislative step that seeks to curtail executive power in military engagements, emphasizing the need for Congressional approval. This act has garnered support from other Senators, indicating a broader concern among some lawmakers regarding potential military escalation in the Middle East (source-2).
Critics of Sanders may argue that his views are overly cautious or politically motivated, particularly given the complex geopolitical situation involving Iran and Israel. However, the historical context of U.S. involvement in Middle Eastern conflicts, particularly those initiated without clear Congressional authorization, lends credibility to Sanders' warnings (source-3).
Moreover, Sanders' comments about Netanyahu being a "war criminal" under indictment by the International Criminal Court reflect a broader critique of Israeli policies and actions, which some may view as biased. However, this perspective is rooted in documented international legal proceedings and criticisms from various human rights organizations (source-1).
Conclusion
The claim that Senator Sanders warns against U.S. involvement in Netanyahu's war against Iran is True. His statements and legislative actions clearly articulate a stance against military engagement without Congressional approval, underscoring the importance of adhering to constitutional processes regarding war powers. Sanders' warnings are grounded in a legal and historical context that highlights the risks of unchecked military action.
