How did the Charlie Hebdo attack in January 2015 affect French counterterrorism efforts?

The January 2015 attack on the offices of the satiric magazine Charlie Hebdo prompted a significant shift in French domestic security policy. In response to the tragedy, French President François Hollande pledged more than $850 million in additional funding to bolster national counterterrorism efforts.1

This investment marked a dramatic increase in domestic security spending aimed at addressing the threat posed by militant extremism. Despite these heightened measures, the government continued to face challenges in preventing subsequent violence, including a thwarted attack on a high-speed train later that same year. Furthermore, the period following the attacks saw a concerning rise in Islamophobic incidents within France, which necessitated a focus on maintaining social cohesion alongside the state's security operations.12
