US intelligence sources estimate that Iran still possesses between 1,500 and 2,500 missiles, contrary to President Trump's claims that Tehran's military capabilities have been destroyed.

The assessment has become a factor in the Trump administration's debate over whether to resume large-scale strikes against Iran, although intelligence officials acknowledge uncertainty about the exact stockpile.
