Answer: United States
Notes: The United States carried out large-scale airstrikes against ISIS targets in Syria under Operation Hawkeye. The strikes followed an ISIS ambush in Palmyra that killed two US soldiers and a civilian interpreter. Operation Hawkeye is a US-led counter-terrorism mission using air and precision strikes against Islamic State (ISIS) targets in Syria. The operation was launched by the United States under President Donald Trump and executed through US Central Command (CENTCOM) in December 2025. Its aims are to avenge the Palmyra attack, degrade ISIS networks, prevent regrouping, protect US and coalition forces, and signal that attacks on US personnel will face direct retaliation.
