President Donald Trump has played tough with Iran, using the U.S. military to punish that nation’s Islamist regime when it stops talking, and calling off hostile actions when Iran returns to the negotiating table. After five months of this pattern, Americans’ support for U.S. attacks on Iran is lukewarm at best, the latest I&I/TIPP Poll shows.
For the August online national I&I/TIPP Poll, taken from July 28 to Aug. 1, 1,463 adults were asked: “Do you support or oppose U.S. military action against Iran?” The poll’s margin of error is +/-2.9 percentage points.
A total of 42% said they supported military action either “strongly” (22%) or “somewhat,” while a 44% plurality said they opposed it “strongly” (28%) or “somewhat” (16%). Another 14% said they were not sure.

As usual, responses by political affiliation show a gap in how the main political parties and independents view the Iran conflict. A big majority of Democrats were against the U.S. attacks on Iran (68% oppose, 21% support), while a smaller plurality of independents (47% oppose, 34% support) also reject it.
Republicans reverse-flip the Dems’ response: A large GOP majority (71% support, 21% oppose) back Trump’s military action against Iran. Indeed, among all 36 demographic groups in the I&I/TIPP Poll, the Republicans’ 71% support is the largest of all.
Notable differences also emerge when looking at responses by gender and income.
Men largely back the Iran war (52% support, 40% oppose), while a significant plurality of women oppose it (32% support, 48% oppose).
Meanwhile, among I&I/TIPP’s four general income categories, the bottom three income levels average just 39% support for the Iran conflict vs. 47% opposition, but a majority in the highest income bracket solidly back the Iran war effort (52% support, 39% oppose).
I&I/TIPP’s second question asks: “If Iran refuses to negotiate over its nuclear program, would you support or oppose expanding U.S. military operations against Iran?”
On this question, Iranian refusal to negotiate its nuclear program increases support for enlarging the military response against Iran. Overall, 47% said they’d either “strongly support” (25%) or “somewhat support” (22%) increased military action, compared to just 36% who “strongly oppose” (23%) or “somewhat oppose” (13%) that. Another 17% weren’t sure.

Political party membership is once again a defining factor. Only the Democrats outright oppose expanding the U.S. military response (29% support, 55% oppose). Independents are slightly in favor (40% support, 38% oppose). But Republicans are all in on ratcheting up military action if nuke talks fail: 74% support, just 17% oppose.
A third and final question asks: “If Iran refuses to negotiate over its nuclear program, which approach would you prefer?” Respondents were asked to choose one of five possible answers.
Of the five, both “Continue diplomatic efforts without expanding military operations” and “Withdraw U.S. military forces from the conflict” were each picked by 22% of participants, while “Continue air and missile strikes, but do not send U.S. ground troops” won 19% backing. Least popular answer, at 17%, was “Expand military operations, including ground troops if necessary.”
Meanwhile, a hefty 20% said they weren’t sure.

Among Democrats, 62% favored responses including either continuing diplomacy (31%) or withdrawal of forces (also 31%). Republicans, on the other hand, 57% backed either missile strikes but no more ground troops (28%) or expanded operations with ground troops (29%).
Independents 45% supported either more diplomacy (22%) or withdrawal (23%), but 23% also said they were “not sure.”
All in all, politically speaking, there’s not a large amount of backing specifically for either missile strikes or more ground troops in the region. Still, when asked separately whether they would support expanding U.S. military operations if Iran refuses to negotiate over its nuclear program, 47% said yes, compared with 36% who opposed doing so.
Right now, talks with Iran over control of the Strait of Hormuz and its nuclear program are at an impasse.
Iran has threatened to close the Strait of Hormuz to commercial shipping unless the U.S. meets what the New York Times described as a “sweeping set of demands.”
Specifically, Iran called for the U.S. “to lift its naval blockade and sanctions on Iran, withdraw the U.S. military from around Iran, pay war reparations and release frozen Iranian assets, as well as end attacks on Iran’s allies in the region and threats against the country,” the Times reported.
For the U.S., in addition to ending Iran’s control of Hormuz, a linchpin for a final deal includes Iran giving up its stores of highly enriched uranium, which can be used to make a bomb.
There’s little doubt that the destabilizing effects of an Iranian nuclear weapon would be enormous.
“The regional implications of a nuclear Iran extend well beyond the immediate threat of weapons use,” according to a recent analysis by Political.org, which notes that Saudi Arabia has vowed to pursue a nuclear weapon if Iran gets one.
That, in turn, “could trigger a cascade of nuclear proliferation across the Middle East involving Turkey, Egypt, and the United Arab Emirates.”
That’s a nuclear nightmare that President Trump hopes to avoid.
Meanwhile, Israel is thought to have anywhere from 100 to 400 nuclear warheads already. It has stated repeatedly that it won’t let Iran get a nuclear weapon, seeing a nuke in the hands of a radical Islamist regime as an existential threat.
American voters also aren’t happy about Iran’s nuclear ambitions, but they are also not keen on further military action, especially involving ground troops. The memories of the Iraq War and the 20-year Afghanistan war, not to mention the terrorist 9-11 attacks, still weigh heavily on public opinion, as this I&I/TIPP Poll suggests.

While I support President Trump on everything unequivocally (economics and the financial situation; social matters; law and voting rights etc), I am grudging on my support for him on Iran.
And this is the reason: He tells us how evil the Iran Government is and yet he plays paddycake by continuing to try to negotiate with them. The government is a manifest liar, time and time again, so why is he wasting time and our munitions (which are being used up) by not destroying Iran entirely?
He says time and time again that Iran will be so dangerous if they go after their nuclear bomb-but then he gives them time so that they can go after their nuclear bomb(s). And this happens repeatedly.
My opinion is this: He should explain the answers to the above questions and comments. I really don’t understand the reasons he doesn’t. All he says is that we will give the Iranian Government-who he terms and everybody knows is evil and malevolent-another chance. Why????
He may have a good plan and a good reason, but he is leaving his supporters in the dark. We support him because he generally fights back-but in what is a real threat to America (he says) he is not fighting back. He is negotiating again and again with an Iranian Government that lies and cheats on the preceding negotiations and so-called treaties that Iran signs and breaks-with impunity.
Doesn’t Pres. Trump see this?
