Former US President Barack Obama has unleashed a sharp critique of Donald Trump's handling of the Iran war, labeling it a "costly mistake" and questioning the billions of dollars spent with little to show for it.

In a television interview, the two-time President claimed that America is now no better off than it was before the war began. Obama emphasized that the United States spent billions of dollars, put enormous strain on its military, and suffered significant loss of life during the conflict.

"We spent billions of dollars, put enormous strain on our military, and suffered significant loss of life - for what?" Obama reportedly asked during the interview, showing no mercy toward Trump's Iran policy.

His comments come at a particularly sensitive time, as Trump celebrates a newly signed ceasefire and diplomatic agreement with Iran, portraying it as a major foreign policy achievement. The timing of Obama's criticism suggests a political dimension to the debate over the Iran deal.

The former president's remarks highlight the ongoing debate surrounding US foreign policy in the Middle East and the contested legacy of Trump's approach to Iran. The criticism underscores the financial and human costs associated with the years of conflict, while also raising questions about the long-term strategic benefits of the recent diplomatic breakthrough.
