The purpose of this legislation is to establish clear guidelines regarding the deployment of U.S. troops to Greenland. Specifically, it aims to ensure that no American military personnel can be sent to Greenland unless the Kingdom of Denmark explicitly invites them. This reflects a commitment to respecting the sovereignty of Denmark and its territories. The key provisions of this legislation include a prohibition on the deployment or assignment of U.S. Armed Forces to Greenland without an invitation from Denmark.
