The United States wishes to make its position on the announced referendum in Trieste perfectly clear: the referendum is a violation of international law unless sanctioned by the United Nations Security Council. The division of Trieste into two separate zones with military administration was authorized by the Security Council and remains in place at the will and pleasure of the United Nations. No referendum held without consent of the UNSC can be valid, regardless of the outcome. Especially a referendum that takes place only in a particular part of Trieste and without regard for the remaining population in Zone A.
The United States is willing to take part in frank and meaningful discussions with regional powers including Italy and Yugoslavia in regards to the future of Trieste but American troops will remain in Zone A to administer and protect the zone in compliance with standing U.N. authorization.
