He said the escalation could have been avoided, reacting in an X (formerly Twitter) post to Washington's attack on more than 80 targets allegedly linked to Iran's Revolutionary Guard (IRGC) in Iraq and Syria in a wide-ranging air assault.

US Central Command says it hit 85 Iranian-linked targets in Syria and Iraq in retaliation against the recent "Iran-affiliated" fighters' attack that killed three US servicemen in Jordan. President Joe Biden's X post read that the US does not "seek conflict in the Middle East or anywhere else in the world. But to all those who seek to do us harm: We will respond," despite Iran denying involvement in the incident.

"If we 'do not seek conflict,' then let's get the troops out of there," Kennedy said, apparently reacting to Biden's statement. "They are not welcome. They are not needed," he added.

Kennedy claimed that the current escalation would not have been necessary if Washington hadn't put its military "in the crosshairs" of Shiite militias. He described the existence of these groups "as a legacy of our illegal war in Iraq." He recalled that both Iraq and Syria had asked the US troops to leave their territory while Iran would not tolerate America's military presence on its borders.

Besides pulling US troops "out of the Mideast," Kennedy urged Washington to forge ties with regional powers instead. The presidential candidate also described the troop presence in the area as "indefensible targets for anyone in the region who wants to provoke a conflict."

Iraq has rebuked the US over the airstrikes, saying they constitute "a violation of Iraqi sovereignty" and "pose a threat that could lead Iraq and the region into dire consequences. The Syrian military, as quoted by SANA news agency, denounced the raid as "the aggression of the American occupation forces."
