The United States deploys two types of submarines -- attack submarines and ballistic submarines  Attack submarines carry cruise missiles to attack specific locations on land, and they are also used to spy on foreign countries  Ballistic submarines carry intercontinental ballistic missiles that deliver nuclear missiles at a minimum range of 3, 400 miles  Consequently, there is little advantage to placing a ballistic submarine near the coast of any country  Both submarines are nuclear-powered, but only the ballistic submarines carry nuclear weapons  The United States believes that a foreign country is plotting to attack her homeland, but more intelligence must be collected

The United States should pre-emptively attack the foreign country to best defend itself.
