During 1969, growing GI dissent intersected with movement outreach and the opening of new coffeehouses to expand civilian/military collaboration. More government leaders publicly supported antiwar activism. The Woodstock festival was the most visible sign of increased overlap between political and cultural dissent. Various elements of the movement coalesced into the most spectacular outpouring of antiwar passion in the nation’s history during the October Moratorium. Repression of the antiwar movement escalated under the Nixon administration. Activists faced local red squads and vigilante attacks on GI coffeehouses, as well as administration threats against the media, conspiracy trials, and intelligence agencies using COINTELPRO and Operation CHAOS. The president’s fear of stimulating additional antiwar sentiment contributed to his decision to keep secret his expansion of the air war into Cambodia. National Security Advisor Henry Kissinger met with various dissenting groups to buy additional time. Once Nixon developed his Vietnamization policy, it forced the movement to adapt to new circumstances, but local grassroots activism and conventional dissent persisted.
