Summary

From 1969 to 1971, Canadian activists, led by the Society for Pollution and Environmental Control (SPEC) and the Don’t Make a Wave Committee (DMAW), campaigned to stop U.S. nuclear tests on Amchitka Island, Alaska. Despite widespread protests, border blockades, a voyage by the Greenpeace ship, and legal challenges, the U.S. detonated the Cannikin bomb in November 1971. However, the campaign helped end testing on Amchitka and led to the formation of Greenpeace.

Background

The United States planned underground nuclear tests on Amchitka Island, Alaska, a former wildlife refuge, as part of the arms race with the Soviet Union. The first test in 1965 caused environmental damage and raised fears of earthquakes and tsunamis due to the island’s location on a fault line. In 1969, the U.S. announced the Milrow test, and later the larger Cannikin test, prompting Canadian activists to organize opposition.

What happened

In September 1969, SPEC organized protests at the U.S. [source: nv-database] consulate in Vancouver, using signs like ‘Don’t make a wave’ [source: nv-database]. In October, 6,000 people demonstrated at Peace Arch Park on the Canada/U.S. [source: nv-database] border, blockading traffic for an hour [source: nv-database]. Despite protests, the Milrow test proceeded, causing a 6.9 magnitude shockwave that drained lakes and killed wildlife [source: nv-database]. After the Cannikin test was announced for 1971, DMAW formed and planned to sail a boat into the test zone [source: nv-database]. They raised funds through a benefit concert in October 1970, netting $17,000 [source: nv-database]. In September 1971, the Greenpeace set sail but was arrested by the U.S. [source: nv-database] Coast Guard; the crew received a supportive letter from the arresting sailors [source: nv-database]. Protests escalated with thousands blockading borders, student strikes, and a half-hour work stoppage by 150,000 union members in British Columbia [source: nv-database]. A petition with 177,000 signatures was delivered to the White House [source: nv-database]. The U.S. [source: nv-database] Supreme Court voted 4-3 in favor of the test on November 6, 1971, and the bomb was detonated hours later, causing extensive environmental damage [source: nv-database]. In February 1972, the AEC abandoned the Amchitka test site for ‘political and other reasons’ [source: nv-database].

Tactics used

The campaign combined public protests, border blockades, and a high-profile nonviolent voyage to draw media attention and pressure the U.S. government, while petitions and strikes mobilized broad public support. [source: nv-database]

Outcome

Verdict: partial.

The campaign failed to stop the Cannikin test, but it achieved partial success as no further tests were conducted on Amchitka, and the island was returned to wildlife refuge status. The DMAW committee evolved into Greenpeace, which continued environmental activism. [source: nv-database]

Lessons

  • A dramatic nonviolent action, like sailing into a test zone, can generate significant media coverage and public sympathy.
  • Building a broad coalition of students, unions, scientists, and international allies amplifies pressure on the target.
  • Even if the immediate goal is not achieved, sustained campaigning can lead to long-term policy changes and organizational growth.
