"To preserve and uphold U.S. economic security and prosperity, and secure our border, the U.S. Department of Homeland Security (DHS) must facilitate lawful trade and travel, reduce security risks and vulnerabilities, and promote cross-border resiliency and collaborative partnerships. In 2017, DHS conducted an assessment of Northern Border security and concluded that while the Northern Border remains an area of limited threat in comparison to the U.S. Southern Border, safeguarding and securing the Northern Border presents unique challenges. The most common threat to U.S. public safety along the Northern Border continues to be the bi-directional flow of illicit drugs. The Strategy articulates three main goals with key objectives identified under each goal: GOAL 1: Enhance Border Security Operations; GOAL 2: Facilitate and Safeguard Lawful Trade and Travel; GOAL 3: Promote Cross-border Resilience ."
