In the end events as usual took control. The Soviet-inspired Committee for the Defence of Yugoslavia staged an abortive foray into Slovenia, precipitating a collision between the Slovenian provincial government and the federal government in Belgrade. The Committee called for Soviet help. At the same time some bakeries closed in Gdansk and Dresden due to diversion of fuel to factories producing military transport, and the resultant riots threatened to get out of hand. Soviet reaction was seen to be unavoidable. The hard-liners won the day.
Meanwhile, the manoeuvre season had arrived. The Soviet command was staging two major exercises, one in Hungary and one of unprecedented size in East Germany. The Final Act signed at the Conference on Security and Co-operation in Europe required the notification of manoeuvres over a certain size and encouraged states holding them to invite observers from other countries. The Russians played this in two ways. On grounds that they were of relatively little importance they failed to notify the Hungarian manoeuvres, believing that these might be the first to be converted into the real thing, but notified the German exercise through the normal channels.
On 27 July 1985 a Soviet airborne division in an unopposed landing secured the approaches to Belgrade. At the same time a Soviet motor-rifle division from Hungary crossed the Yugoslav border on the Budapest-Zagreb road, followed by another. The pro-Soviet Committee was recognized as the provisional government of Yugoslavia, and Yugoslav frontier forces, after a short engagement, were quickly obliged to withdraw towards Zagreb. The Soviet plan was to occupy Zagreb and thence link up with the airborne troops east to Belgrade and fan out west to Ljubljana. Meanwhile, the exercises in East Germany intensified, with more formations moving forward from the Western Military Districts of the Soviet Union through Poland.
The NATO side, in spite of many warnings, had failed to make specific provision for this kind of threat in Yugoslavia. That country had remained the ‘grey area’ par excellence. It was not covered by the NATO commitment to automatic defence. But equally the West had not renounced interest in what happened there, as they had by implication in Hungary in 1956 and Czechoslovakia in 1968. The continued neutrality of Yugoslavia was obviously a Western interest of prime importance. But it is difficult to guarantee a country whose foreign policy is based on non-commitment, as Britain and France had found with Belgium prior to 1939. Therefore greyness was made a virtue: the very uncertainty of Western reaction was made a principle of deterrence.
The grey chicken now came home to roost and NATO had to decide — or rather the USA decided, with reluctant Italian acquiescence, while NATO tagged along. In the hope of favourable Yugoslav reaction, and in view of all the long history of Italian-Yugoslav conflict, it was vital to avoid the use of Italian forces. But after some days of furious diplomacy in Belgrade, Zagreb and Ljubljana, US marines and airborne forces from Italy were able to make unopposed landings at Rijeka (Fiume), Ljubljana and some of the Dalmatian islands. What was much more serious, within twenty-four hours they were in action against Soviet airborne and armoured units.
At this stage the US government still harboured a final hope that they might be able to isolate events in Yugoslavia from the wider European scene, and above all that they might be able to limit the impact upon American public opinion of any fighting there. They called for an immediate meeting of the Security Council. They ordered their commanders in the first instance not to move beyond the boundaries of Slovenia, and, to prevent the inflaming of opinion in the United States, to put an immediate ban on all television coverage of their operations.
But they were too late. They had counted without the enterprise of a resolute Italian television cameraman, Mario Salvadori. He was not employed by the official Italian television service, RAI, but by an international newsfilm agency. He had at one time lived in the States. In Italy he had made good friends among the American marines, whose peacetime manoeuvres and parades had provided him with useful material when other news was scarce. He happened to be at their base when the alert began, and his friends took him along ‘for the ride’ when they were airlifted to Ljubljana.
