Since 2021, the sustained escalation of terrorist violence in Pakistan is linked to which regional event?

💡 Explanation:

The five-year sustained escalation of terrorist violence in Pakistan since 2021 is strongly correlated with the return of the Taliban to power in Afghanistan (August 2021), which is widely reported to have strengthened militant groups like the TTP and provided them operational space. This event marked a major shift in Pakistan's security dynamics and regional leverage.
