“ In the last year, the free world has seen major gains for the system of collective security: the accession to the North Atlantic Treaty Organization and Western European Union of the sovereign Federal German Republic; the developing cooperation under the Southeast Asia Collective Defense Treaty; and the formation in the Middle East of the Baghdad Pact among Turkey, Iraq, Iran, Pakistan and the United Kingdom.
