Abstract
Over the last decade, Pakistan has taken significant measures to combat terrorism and extremism. However, the U.S. frenzied retreat from Afghanistan altered Pakistan's security apparatus. The Taliban's takeover of Afghanistan has had a significant effect on Pakistan’s security, leading to the resurgence of Tehreek-eTaliban Pakistan (TTP). With the clear objective of implementing Sharia law in Pakistan, TTP has regained its strength and power. The militant outfit has emerged as a massive threat due to its potential for chaos, extremism, and instability. The article would explain the shameless and long record of rapacity of TTP in Pakistan. The research critically evaluates the factors contributing to the resurgence of TTP in Pakistan for instance withdrawal of US and NATO (North Atlantic Treaty Organization) Forces, change of leadership, reconstruction of organizational structure, and socio-economic disparity. The research rolls in three sections; First and foremost, it critically evaluates TTP's evolution, rise, decline, and revival. Secondly, it examines the challenges and threats posed by TTP to Pakistan. After regaining its strength and support base, TTP intensified its operation activity and attacks on Pakistan’s security, stability, and sovereignty. Lastly, this research paper would argue that the state must implement effective counter-terrorism measures and a de-radicalization plan to counter the reorganization of the militants. To protect the sovereignty of the state, militant groups like TTP must be eliminated by intervention, urgency, diplomatic engagement, and regional cooperation.
