How did France respond militarily after the Paris attacks of 2015?

Following the terrorist attacks in Paris in November 2015, which President François Hollande characterized as an act of war, France significantly escalated its military response against the Islamic State in Iraq and the Levant (ISIL).1

Key military and security actions included:

• Retaliatory Airstrikes: On November 15, 2015, French warplanes launched a series of strikes against ISIL’s de facto capital of Al-Raqqah, Syria, marking a dramatic intensification of France's intervention in the Syrian Civil War.1
• Naval Deployment: The aircraft carrier Charles de Gaulle was dispatched to the eastern Mediterranean to bolster the military campaign against ISIL.1
• Domestic Operations: French security forces, including the elite Groupe d’Intervention de la Gendarmerie Nationale (GIGN), conducted extensive raids across the country, most notably a major operation in Saint-Denis to neutralize suspects involved in the attacks.1
• International Coalition Building: President Hollande engaged in diplomatic efforts, including meetings with U.S. President Barack Obama, to strengthen the international anti-ISIL coalition.1

These actions were part of a broader, sustained effort to dismantle the network responsible for the violence and to degrade ISIL's operational capabilities.1
