During Operation DESERT STORM, a relatively small amphibious force of 17,000 embarked Marines caused the Iraqis to commit approximately how many soldiers to defend against invasion?

• A. 60,000
• B. 100,000
• C. 80,000
• D. 120,000

Answer: (C)

Deterrence works when a smaller force signals a credible threat of a large, decisive response, pushing an adversary to mobilize far more than would be needed for a routine defense. In this scenario, a 17,000-strong amphibious Marines force demonstrated a capable, high-stakes option for invasion, which led Iraq to treat the threat as real and respond by fielding a substantial defensive force. Roughly 80,000 Iraqi soldiers were committed to defend against invasion, a much larger mobilization than the initial force would suggest and a clear illustration of how a credible, forceful signal can compel a disproportionate defensive reaction. The exact numbers vary by source, but the core idea is that a relatively small, credible threat can provoke a significantly larger defensive commitment.
