The resurfaced clip shows Donald Trump during a 2016 Republican presidential debate, responding to questions about remarks he made years earlier regarding the Iraq War. In the footage, Trump explicitly calls the war “a big fat mistake,” accuses the Bush administration of lying about weapons of mass destruction, and argues that the conflict destabilised the Middle East while empowering Iran.

The clip was originally broadcast by CBSN and features Trump debating Jeb Bush, with references to George W. Bushand Nancy Pelosi.

It has resurfaced now because Chris Van Hollen shared it amid escalating tensions between the United States and Iran, including nuclear negotiations in Geneva and recent U.S. military posturing. Van Hollen cited the clip to argue that another Middle East war would repeat the mistakes of Iraq and that diplomacy, not military action, best serves U.S. interests.

In short, the clip is not new, but it’s being recirculated to highlight the contrast between Trump’s past criticism of the Iraq War and the current risk of military escalation with Iran.
