By PHILLIP WALTER WELLMAN | STARS AND STRIPES Published: May 19, 2021 KABUL, Afghanistan The son of one of Afghanistan’s most renowned guerrilla leaders is working to unite disparate militias against the Taliban, fearing the group may try to regain control of the country after U.S. and coalition forces exit. Ahmad Massoud, 32, whose father was the late Northern Alliance commander Ahmad Shah Massoud, said over 100,000 militia leaders, fighters and other stakeholders in northern Afghanistan have so far pledged support to his movement. But by operating separately from the government, critics say the movement, dubbed “Resistance 2.0,” risks deepening divisions that could make the fall of the government and national security forces more likely.
