Iraq also made extensive use of front companies, middlemen, secret ownership of all or part of companies all over the world, forged end-user certificates, and other methods to hide what it was acquiring. Some transactions may have involved people, shipping, and manufacturing in as many as 10 countries. Support from Great Britain exemplified the methods by which Iraq would circumvent export controls. Iraq bought at least one British company with operations in the United Kingdom and the United States, and had a complex relationship with France and the Soviet Union, its major suppliers of actual weapons. Turkey took action against the Kurds in 1986, alleging they were attacking the Kurdistan Workers' Party (PKK), which prompted a harsh diplomatic intervention by Iran, which planned a new offensive against Iraq at the time and were counting on the support of Kurdish factions.
