The Trump Admin’s Global Campaign Against ‘Radical Left Terrorism’ Is Built on a National Security Memo Without Congressional Approval

A little-noticed presidential national security directive is now the legal engine behind a wave of terrorism prosecutions against left-wing protesters.

That domestic campaign now has an international dimension, one that American officials had been planning for months, culminating on July 16, 2026, when Secretary of State Marco Rubio’s Ministerial on the Resurgence of Political Terrorism drew representatives from more than 65 countries to Washington. The gathering was informally called the “Antifa summit.”

Rubio described antifa-aligned networks as sharing infrastructure across borders and accused Iran and Cuba of helping bankroll the movement, without offering evidence. The White House declared the summit the start of an “unprecedented global offensive” against what it calls “radical left terrorism.”

This offensive is built on the same domestic legal architecture that has now sent American activists to prison for decades.

That architecture is National Security Presidential Memorandum/NSPM-7, issued on Sept. 25, 2025, which for the first time appeared to authorize preemptive law enforcement measures against Americans based not on whether they are planning to commit violence but for their political or ideological beliefs.

Nearly a year later, that blueprint has moved from paper into practice.
