In Nevada, protesters have forced the Bush administration to indefinitely postpone a controversial bomb test designed to help the military better understand nuclear bunker busters. The government had planned to set off 700 tons of explosives in the Nevada Test Site creating an explosion 50 times more powerful than the Army’s largest conventional bomb. According to government documents, the test — known as Divine Strake — was needed to determine the “proper nuclear yield necessary to destroy underground facilities.” The Pentagon estimated the blast would have been so large that it would have created a 10,000 foot-high mushroom cloud. Critics called for the government to cancel the test because they feared the mushroom cloud would contain radioactive dust from old nuclear tests.
