Final answer:
To intercept Weapons of Mass Destruction heading for the U.S., a combination of satellite imagery, electronic surveillance, human intelligence, and international cooperation is utilized. Agencies like the Defense National Stockpile Center support these efforts domestically.
Step-by-step explanation:
What intelligence resources might we use to intercept an unspecified WMD known to be coming to the U.S. mainland? To detect and intercept Weapons of Mass Destruction (WMDs), the United States utilizes a broad array of intelligence resources, including satellite imagery, electronic surveillance, and human intelligence (HUMINT). These resources help gather information about potential weapon deliveries, the movement of dangerous materials, and any unusual activities that might signal a threat. Additionally, the U.S. involves international cooperation through agencies such as the United Nations, which has bodies like the International Atomic Energy Agency that assist in monitoring and controlling the spread of nuclear materials. Domestic agencies like the Defense National Stockpile Center ensure that reserve materials necessary for national defense are available in times of crisis. The history of such intelligence efforts traces back to concerns over Saddam Hussein's Iraq and its potential WMD capabilities, highlighting the continued importance of reliable intelligence and international coalitions to counter such serious threats.
