A .11111111111111111111111111111111111.THE FOUR MONTONEROS ENTERED THE
COUNTRY USING THEIR OWN NAMES, DID NOT KNOW IF THE 601ST BATTALION
HAD RECEIVED ADVANCE INFORMATION ABOUT THEIR EXPECTED ARRIVAL.
B. OVER THE PAST YEAR OR SO, ARGENTINE SECURITY AND
INTELLIGENCE SERVICES HAVE GROWN INCREASINGLY CONCERNED OVER THE
POSSIBILITY OF RENEWED TERRORIST ACTIVITIES, ESPECIALLY BY THE
MONTONEROS; THIS CONCERN, WHICH WAS ORIGINALLY CAUSED BY THE. -
GROWING ECONOMIC PROBLEMS, IS LIKELY TO INCREASE WITH THE EFFECTS
OF THE ECONOMIC AND POLITICAL PROBLEMS CAUSED BY THE ARGENTINE
DEFEAT IN THE FALKLANDS. HOWEVER, THERE IS NO INDEPENDENT �
CONFIRMATION OF AN INCREASE IN MONTONERO PRESENCE OR ACTIVITIES
IN ARGENTINA.)
