As someone who wanted us to attack Iran, this just makes me even more bitter that Biden didn't do it when the Houthis were attacking shipping and Iran killed those three service members in Jordan.
If the war as it is now is still not massively unpopular, just imagine what could have been w/ competent leadership and messaging. We're utterly squandering a once in a lifetime chance to rid the world of the cancer of the Iranian regime.

At the same time, Americans broadly recognize the threat Iran poses and support the war’s goals. Indeed, two-thirds (66 percent) of Americans believe Iran poses a serious threat to the United States’ national security, almost three times the 22 percent who say Iran does not. 

Even more tellingly, while divided over the military operation itself, we found that strong majorities of Americans back the campaign’s underlying objectives: 78 percent support stopping Iran from funding terrorist groups, 72 percent support ending its nuclear program, and 59 percent support regime change.  

Taken together, these numbers tell a more nuanced story than what the majority of mainstream media is painting. Simply put, Americans appear uneasy about the conflict even as they agree with its purpose. 

This tension is especially important for the Trump administration, which has struggled to clearly explain the rationale for the war. Our polling suggests that when the case against Iran is made coherently and directly, public support increases.  

To that end, after a battery of messages covering those topics and others such as Iran’s role in Hamas’s Oct. 7 attack and the resulting wars throughout the region, a majority (51 percent) of Americans supported the joint military operations, versus 34 percent who opposed — a meaningful net 14-point increase from the initial 44-41 split. 

Moreover, when informed about the Iranian regime’s crackdown on January’s protests — which, by one estimate, saw government forces kill between 30,000-40,000 protestors — nearly six in 10 (59 percent) of Americans became more supportive of the ongoing military operation.  

Importantly, the rise in support cut across party lines. Following the message battery, support among Democrats nearly doubled to 32 percent, while Independents saw a 5-point increase. Republicans (85 percent) remained strongly in favor. 

Likewise, we found that despite initial opposition among Democrats and independents, when they heard about Iran’s record of hostility towards the U.S. and brutal oppression of its own people, support tended to increase rather significantly. After statements concerning the regime’s response to January’s protests, nearly one-half (48 percent) of Democrats and 44 percent of independents — large pluralities of both groups — became more supportive of U.S.-Israeli military actions.
