NEED TO KNOW

• 80% of voters under 30 say there were not sufficient reasons for the airstrikes.
• 61% of all Americans under 35 oppose U.S. military action in Iran.
• Even young Trump voters are publicly breaking with the war.

MILWAUKEE, WI (TDR) — A new Marquette Law School Poll shows 80% of Americans aged 18 to 29 say the airstrikes against Iran were not justified, the highest rejection of any age cohort and a number that scrambles the war's political logic.

The big picture: This is the first generation with no memory of a country not at war in the Middle East.

• Voters under 30 came of age after Iraq, after Afghanistan, after Libya
• Their lifetime average for U.S. ground presence in the region is roughly 100%
• The Marquette number tracks with long-running research showing the post-9/11 generation views military force differently than their parents

Why it matters: The opposition isn't ideological. It's experiential, and it crosses the MAGA line cleanly.

• Republicans face a midterm cycle where every House seat and 35 Senate seats are up
• Trump's 2024 coalition included a meaningful share of young men who broke with the Democratic Party

Driving the news: The survey of 982 adults ran April 8–16, with a margin of error of plus or minus 3.4 points.

• 63% of Americans overall say the war lacked sufficient justification
• 78% say the U.S. has not achieved its goals
• 75% approve of the April 7 cease-fire

What they're saying: Young conservatives are increasingly willing to say what GOP leadership won't.

• Carson Carpenter, 20, co-founder of Off The Record USA — told TIME the war evokes post-9/11 conflicts that cost 7,000 American lives and trillions of dollars
• James Cox, 20, D.C. College Republicans Chief of Staff — estimated about half of his peers disagree with how Trump has handled the conflict
• Adam Mockler, podcaster — told CNN young people "have been told this will make us safer" before, and aren't buying it again

Yes, but: Young voters historically turn out at lower rates than older cohorts, and the White House will lean on that arithmetic.

• 18-to-29 turnout in midterms typically lags seniors by 20 points or more
• A separate Angus Reid survey found 85% of self-identified MAGA voters supported the initial strikes — meaning the generational break is sharpest among Republicans without strong MAGA identity

Between the lines: The forever-war frame is the one Trump himself ran on in 2016 and 2024 — and it's the frame his base is now using against him. Carpenter and Cox aren't quoting Tucker Carlson. They're quoting Trump's own 2016 debate stage, when he called the Iraq War a disaster sold on false pretenses. The political problem isn't that young voters reject the war. It's that they reject it using the candidate's own argument from a decade ago, and the campaign that built a coalition on rejecting forever wars is now defending one.

What's next:

• Republicans defend 35 Senate seats and the full House in November
• Trump approval sits at 39%, a second-term low
• Republican leadership has been conspicuously silent heading into the campaign

If the next generation has only seen wars sold as necessary and remembered as mistakes, what does it take to earn their trust on the next one?
