Just one in four Americans believes President Donald Trump¡¯s war with Iran was worth its costs, and a majority worry that a truce with Tehran is unlikely to last, a Reuters/Ipsos poll found.

The ?five-day poll, which closed on Monday, also showed the war weighing heavily on Trump¡¯s popularity, with his approval rating dropping ?to ?34%, a return to the lowest level of the Republican¡¯s second term that was last touched ?in an April survey.

Only 23% of Americans ¡ª including just half of Republicans ¡ª think the U.S. is now in a stronger position with Iran compared with its position before the war, the poll found. Some 35% of respondents think it is in a ?weaker position. The rest said they were not sure or that the U.S. position was about the same as before. Trump and Iranian President ?Masoud Pezeshkian signed a preliminary deal on June 17 that would reopen oil and gas shipping lanes that were frozen by the conflict, while easing U.S.-led economic pressure on Iran.
