Leftists and radical Islamists have come closer in recent years, drawing on substantial ideological interchange, sharing political space, and infiltrating universities and institutes. Both leftists and Islamists have utilized the ideological frames of anti-globalization, anti-capitalism, anti-colonialism, and anti-imperialism to gain mutual support. Current political thinkers discuss this fast-emerging alliance, which perceives any contrary opinion with utter hostility. It has cracked down on Buddhists, Christians, Ahmadiyyas, and Shias through terrorism, violence, and ethnic cleansing. It has invaded and demolished cultural symbols, as in the Hagia Sophia in Istanbul, Bamiyan in Afghanistan, and elsewhere in South Asia. Twenty-one articles discuss this left-jihadi alliance, which threatens the very existence of diverse ideas and people.
