What's happening there [in Bosnia] merits the use of the word genocide. There is an effort to systematically destroy an entire group. It's even been conceptualized by Serbian nationalists as so-called "ethnic cleansing." That term signifies mass killing, mass relocation, and that does constitute genocide.Lifton regards terrorism as an increasingly serious threat due to the proliferation of nuclear and chemical weapons and totalist ideologies. He has, however, criticized the Bush administration's "War on Terrorism" as a misguided and dangerous attempt to "destroy all vulnerability". His 1999 book, "Destroying the World to Save It," described the apocalyptic terrorist sect Aum Shinrikyo as a forerunner of "the new global terrorism".
