据美国有线电视新闻网（CNN）由SSRS开展的最新民调显示，美国民众对伊朗战争的反对态度愈发坚定，近三分之二的受访者认为美国并未在这场冲突中取胜，且更多人认为唐纳德·特朗普总统没有采取足够措施结束战争。
美国民众对这场战争从未持有积极看法，战争爆发近七个月后，绝大多数受访者认为该冲突损害了美国的国家利益、得不偿失，且总统缺乏明确的应对方案。
此次民调结果公布之际，特朗普正准备在联合国发表讲话，并与海湾国家领导人就伊朗战争的未来举行会晤。与此同时，他也正面临着与伊朗支持的也门胡塞武装日益恶化的危机。
总体而言，仅有29%的美国成年人认可特朗普在外交事务上的处理方式，这是CNN在其两届总统任期内民调中的历史最低值，另有71%的受访者表示不认可。更多人认为，特朗普本届政府的外交政策决策损害了美国的国际形象，而非提升了其地位。仅有26%的受访者认可总统对伊朗局势的处理，较战争爆发后一个月时的33%有所下降。
特朗普在伊朗问题上的支持率下滑主要出现在共和党群体中。在整个冲突期间，民主党人和无党派人士对其的评价一直呈负面状态。但在今年3月，仍有73%的共和党人认可特朗普的处理方式，如今这一比例已降至60%。在共和党及倾向共和党的成年人中，45岁以下群体以及自称不属于“让美国再次伟大”（MAGA）运动的共和党人对特朗普处理伊朗问题的支持率已跌入负值区间，这两类群体分别有53%和54%的人表示不认可。
共和党人对特朗普更广泛外交政策的积极评价也较今年年初有所下降：目前约有一半的共和党人认为特朗普的外交政策决策提升了美国的国际形象，较3月份下降了13个百分点。
如今有四分之三的受访者认为特朗普没有明确的应对伊朗局势的方案，78%的人表示他没有采取足够措施结束战争。约七成受访者认为这场冲突很可能会长期持续，两党多数选民均持此观点。其中32%的人认为这场冲突“极有可能”长期持续，这是战争爆发以来持该看法人数占比最高的一次。
认为战争损害了美国利益的受访者（70%）远多于认为战争带来帮助的受访者（18%），76%的人表示这场战争既不值得美国付出人员伤亡代价，也不值得美国政府背负财政负担。
民主党人和无党派人士几乎一致对这场战争持负面看法，97%的民主党人和82%的无党派人士认为战争得不偿失，且两党中几乎没人认为特朗普在结束战斗方面做得足够多。共和党人在这两个问题上分歧更大：55%的共和党人认为战争的代价是值得的，53%的人认为特朗普在结束战争方面做得足够多。但与其他群体相比，共和党支持者更倾向于认为美国正在赢得战争：70%的共和党支持者持此观点，而独立人士中这一比例为31%，民主党人中仅为13%。
特朗普的战争内阁成员支持率均为负面：国务卿马可·卢比奥支持率为40%，副总统J·D·万斯为36%，国防部长皮特·赫格塞斯为34%。
在共和党群体中，约八成受访者认可卢比奥（81%）和万斯（79%）的工作，赫格塞斯的支持率则为72%。这一差距反映出共和党联盟中非MAGA成员对赫格塞斯存在一定不满。在非MAGA的共和党及倾向共和党的无党派人士中，70%的人认可卢比奥的工作，68%的人认可万斯，而认可赫格塞斯的比例仅为58%。
美国民众对俄罗斯和中国的看法与今年年初基本一致：绝大多数受访者认为这两个国家不友好或是敌对国家。但民调显示，特朗普外交政策关注的多个国家的形象出现了变化。
认为乌克兰是盟友或友好国家的受访者比例从1月份的76%降至了如今的70%。与此相反，如今有更多人认为古巴是友好国家，从1月份的21%上升至26%。
对于加拿大，多数受访者仍认为该国是盟友或友好国家，但在特朗普与这个北美邻国打响关税战后，将加拿大视为盟友的受访者比例从2025年3月的51%降至了如今的38%。这一下滑趋势在两党群体中均有体现，但共和党群体的降幅最为明显（民主党下降9个百分点，无党派人士下降10个百分点，共和党人下降23个百分点）。
将以色列视为盟友或友好国家的受访者比例降至61%，另有15%的人认为以色列是敌对国家，这一比例是CNN自2000年开展民调以来的最高值，约为2025年3月的两倍。这一转变主要出现在民主党及倾向民主党的无党派人士群体中——该群体中有17%的人将以色列视为敌对国家，较2025年3月的8%有所上升。这种看法在年轻群体中也更为集中：45岁以下的美国人中有23%认为以色列是敌对国家，较一年半前的9%大幅上升。

Republican support for Trump’s handling of war in Iran shows cracks in new CNN poll
2026-09-22T09:00:29.632Z / https://www.cnn.com/2026/09/22/politics/cnn-poll-donald-trump-foreign-affairs-iran-war
Americans’ opposition to the war in Iran has hardened, according to a new CNN poll conducted by SSRS, with almost two-thirds saying the US is not winning the conflict and more saying President Donald Trump isn’t doing enough to end it.
Americans have never held positive views about the war, and nearly seven months after it began, broad majorities say the conflict has hurt US interests, has not been worth the costs and that the president lacks a clear plan to handle it.
The findings come as Trump prepares to address the United Nations and meet with Gulf leaders about the future of the Iran war. They also come as he is confronting a metastasizing crisis with the Iran-backed Houthis in Yemen.
Overall, 29% of US adults approve of Trump’s handling of foreign affairs, a new low in CNN polling across both of his terms as president, while 71% say they disapprove. More see his foreign policy decisions this term as harming America’s standing in the world rather than helping it. Only 26% say they approve of the president’s handling of the situation in Iran, down from 33% a month after the war began.
Much of the decline in approval of his handling of Iran comes among Republicans. Views among Democrats and independents have been steadily negative throughout the conflict. In March, though, 73% of Republicans approved of the way Trump was handling it. Now, that figure stands at 60%. Among Republican and Republican-leaning adults, approval of Trump’s handling of Iran dips into negative territory among those younger than 45 (53% disapprove) and those who say they are not members of the Make America Great Again movement (54% disapprove).
Republicans are also less positive now than they were earlier this year about the impact of Trump’s foreign policies more broadly: About half of Republicans now say that his decisions have helped the US’ standing in the world, down 13 points since March.
Three-quarters of all adults now say Trump does not have a clear plan for handling the situation in Iran, and 78% say that he is not doing enough to end the war. About 7 in 10 say it’s at least somewhat likely that the conflict will be a long-term one, including majorities across party lines. About a third, 32%, now see a long-term conflict as very likely, the largest share to say so since the war began.
More say the war has hurt American interests than helped them (70% to 18%), and 76% say the war has not been worth either the toll it has taken in American lives or the financial burden it places on the US government.
Democrats and independents are near universal in their negative views of the war, with 97% of Democrats and 82% of independents saying it hasn’t been worth it. And few in either group see Trump as doing enough to bring the fighting to an end. Republicans are more divided on both questions: 55% say the war has been worth its costs, and 53% that Trump is doing enough to end it. But the president’s partisans are far more likely than others to see the US as winning the war: 70% say so, compared with 31% of independents and 13% of Democrats.
The president’s war Cabinet earns negative approval ratings, with Secretary of State Marco Rubio at 40% approval, Vice President JD Vance at 36% and Secretary of Defense Pete Hegseth at 34%.
Among Republicans, about 8 in 10 approve of Rubio (81%) and Vance (79%), while Hegseth stands at 72% approval. That edge reflects some dissatisfaction with Hegseth among non-MAGA members of the GOP coalition. Among Republicans and Republican-leaning independents who do not support MAGA, 70% approve of Rubio and 68% of Vance, while just 58% approve of Hegseth.
Americans’ views on Russia and China remain largely the same as they were earlier this year: Broad majorities see each as unfriendly or an enemy, but the poll finds shifting views on several countries that have been a focus of Trump’s foreign policies.
The share who view Ukraine as an ally or friendly has dipped from 76% in January to 70% now. On the flip side, more now see Cuba as friendly than did so in January (26%, up from 21%).
On Canada, most continue to see the country as an ally or friendly, but the share who consider it an ally has dropped from 51% in March 2025 to 38% now, in the wake of Trump’s tariff war with our northern neighbor. That drop comes across party lines, but is sharpest among Republicans (down 9 points among Democrats, 10 among independents and 23 among Republicans).
And the share calling Israel an ally or friendly has dropped to 61%, while 15% call it an enemy, the highest share to say so in CNN polling dating to 2000 and roughly double the share who felt that way in March 2025. This shift comes largely among Democrats and Democratic-leaning independents — 17% in that group describe Israel as an enemy, up from 8% in March 2025. This view is also concentrated among younger Americans: 23% of those younger than 45 see Israel as an enemy, up from 9% a year and a half ago.
