the top-secret Huston Plan

Nixon’s first war was against the anti-Vietnam War movement. The president considered it subversive and thought it constrained his ability to prosecute the war in Southeast Asia on his terms. In 1970, he approved the top-secret Huston Plan, authorizing the CIA, the FBI and military intelligence units to intensify electronic surveillance of individuals identified as “domestic security threats.” The plan called for, among other things, intercepting mail and lifting restrictions on “surreptitious entry” — that is, break-ins or “black bag jobs.”
