U.S. General Dan Caine stated on Monday that achieving U.S. military objectives in Iran will be a prolonged and challenging endeavor, with further U.S. casualties anticipated. The U.S.-Israeli air campaign against Iran entered its third day, with no clear end in sight. Kuwait's air defenses mistakenly shot down three American F-15E fighter jets during an Iranian attack. Defense Secretary Pete Hegseth clarified that the operations, aimed at destroying Tehran's missile and naval infrastructure, would not result in an "endless war," despite acknowledging it would not be an overnight completion. President Donald Trump suggested the strikes could last approximately four weeks, while Iran's security chief indicated readiness for a protracted conflict.
