President Reagan and Bush invaded Grenada, Panama, and Nicaragua to protect American interests in the region. In 1983, Reagan ordered the invasion of Grenada to counter perceived threats from a Marxist government. In 1989, Bush launched Operation Just Cause to depose Panamanian leader Manuel Noriega, citing drug trafficking and threats to U.S. citizens.
