The war, launched by Trump alongside US ally Israel in February, has pushed fuel prices sharply higher. This has added to inflationary pressures caused by tariffs on hundreds of imported products.
Trump has defended the conflict as necessary to prevent Iran from acquiring nuclear weapons. He has also argued that tariffs would support American industry by shielding domestic producers from cheaper imports.
Support for cooperation amid impeachment concerns
The survey found broad support among both Democrats and Republicans for cooperation between the president and the incoming Congress.
Large majorities in both parties considered it important for Trump to try to work with Democratic leaders and for those leaders to make an effort to work with him.
However, respondents were more divided over the prospect of the new Congress pursuing impeachment proceedings against the president.
Some 42% believed an attempt to impeach Trump would be bad for the country, compared with 33% who thought it would be good. The remaining respondents were unsure or did not answer.
