It’s a bug. In a jar. A chemically contaminated bug that was a prop in a military exercise held last month in Georgia. Engineers and security police at Moody Air Force Base played out a scenario where “sovereign citizens” used weapons of mass destruction—in the form of contaminated bugs—to attack the base, a trifecta of trickery that melds terrorism, Armageddon, and sedition all into one convenient domestic soup. That bug is the greatest threat to American freedom. Not because of Iran or North Korea or al Qaeda but because of a lazy and thoughtless convergence—that’s the hot word in military circles these days—that can define anyone who does anything as a homegrown terrorist threat. And it’s all about April 19.
