COCOM export controls (1949-1994)
The Coordinating Committee for Multilateral Export Controls, a Western alliance including the US and its European allies, restricted exports of strategic technology to the Soviet bloc. The goal was to deny Moscow the advanced components needed for military systems.
The controls slowed Soviet access to Western technology but were never airtight, with smuggling and espionage filling gaps.
The regime ended in 1994 after the Cold War, but the approach of denying military technology through export controls remains a template.
Today's EU sanctions apply the same logic: deny Russia the Western components its weapons need, and make production slower and costlier.
