US President Joe Biden, with Britain's involvement, authorized further airstrikes in the Middle East, including Iraq, Syria and Yemen, against Iranian-backed militias and the Iranian Revolutionary Guard following a drone attack on a US military base in Jordan that killed three American soldiers. The strikes are in response to repeated attacks on American and international interests by Iranian proxies. National Security Adviser, Jake Sullivan, warned Iran of 'a swift and forceful response' if it directly retaliates, acknowledging that there would likely be further attacks. Iran, Iraq, and Syria have warned of potential retaliation. Republican lawmakers still criticize Biden for his perceived delayed response.
