The 2026 World Cup presents unprecedented security challenges as 48 teams play across 11 U.S. cities, Canada, and Mexico over 39 days. Andrew Giuliani, White House FIFA World Cup Task Force director, calls it "an unbelievable problem set" requiring coordination among more than 400 law enforcement agencies. The tournament's scope dwarfs previous World Cups, with nearly double the teams and matches spread across three countries.

Security planners focus on preventing a repeat of the 2024 Copa America final incident in Miami when ticketless fans rushed gates. FIFA created "last mile" security perimeters with mandatory ticket checks. FBI Deputy Director Christopher Raia expresses concern about homegrown extremists and soft targets like hotels and fan festivals. Host cities received $625 million in federal grants for additional security measures.

Planners address unique fan behaviors and geopolitical tensions given the U.S. is at war with Iran. DHS provided $250 million for anti-drone technology after detecting 400+ unauthorized drone incursions during Paris Olympics. Transportation networks remain vulnerable targets, with anarchist groups already disrupting Italian rail systems during Milan Cortina Olympics. Some threats aim purely to cause disruption without physical harm.
