US President Donald Trump has acknowledged that the war against Iran played a significant role in his Republican Party’s poor performance in the midterm elections, which saw Democrats take control of both chambers of Congress.

In an interview with The Wall Street Journal, Trump said the conflict was one of the major factors behind the Republican losses.

“I think a big part of the loss was the Iran issue. The Iran conflict was definitely one of the reasons,” he told the newspaper.

His remarks came after Republicans suffered substantial electoral setbacks, losing control of both the House of Representatives and the Senate to the opposition Democrats.

Trump had previously promised American voters during his presidential campaign that there would be “no new wars”. However, the war with Iran has continued despite that pledge.

Even after his party’s significant losses in the midterm elections, Trump maintained that launching attacks against Iran had been the right decision.

“I did the right thing. If the situation were to arise again, I would make the same decision,” he told The Wall Street Journal confidently.

The conflict involving Iran has now entered its ninth month. Since its beginning, the war has remained unpopular among many Americans and generated widespread public concern.

Throughout the midterm election campaign, Democratic candidates across the country blamed Trump’s war policy for soaring petroleum prices, inflation and the rising cost of everyday goods.

Trump’s contradictory statements about the war’s objectives and duration also created confusion among voters. At different times, he threatened to intensify US military attacks while simultaneously claiming that he could bring the conflict to an end whenever he chose.

Meanwhile, Tehran has welcomed the Democrats’ sweeping victory in Washington and the Republican Party’s electoral setback.

On Wednesday, Iranian Parliament Speaker Mohammad Bagher Ghalibaf wrote on social media platform X that the American people had directly said no to war.

“The American people have directly said ‘no to war’, and we fully support this clear message,” he said.

With Democrats gaining control of both chambers of Congress, analysts believe Trump’s war policy, defence budget and authority to launch unilateral military action against Iran could face greater scrutiny, congressional investigations and legal challenges.
