The Third World War: The Untold Story

When the American strategic nuclear superiority in the 1960s gave way to the state of rough parity between the two superpowers, their vulnerability to each other’s inter-continental weapons was perhaps of less importance in the Alliance than the vulnerability to nuclear attack of the European allies. Whatever marginal advantage might accrue to either superpower from improved accuracy, the hardening or concealment of launchers, their increased mobility and so on, the simple fact remained that neither could be so hard hit by the other in a first strike as to be incapable of a devastating response. The critical question that began to emerge in the seventies was how far the US would be induced by the difficulties of the European allies in wartime to initiate a central attack on the Soviet Union. If the willingness of any American president to invite the appalling reprisals this would produce would be questionable (as it could hardly fail to be), what could be done to find an acceptable alternative? Thus was born, out of European uncertainty whether the USA could be relied upon to accept truly appalling damage at home on behalf of allies abroad, the debate on TNF and their modernization, a debate which did much to throw the Alliance into disarray and to offer the Soviet Union opportunities it did not fail to exploit.

The introduction into service by the USSR of the SS-20 ballistic missile and the Backfire bomber (to use the NATO term) in the late 1970s gave the Warsaw Pact new options for an attack on Western Europe, although Soviet military thinking saw this as only a continuance of an established line of policy. It was now possible, given the SS-20’s range of 3–4,000 miles (as against 1–2,500 for the SS-4 and 5 it was replacing), for the USSR to attack almost any major target in Western Europe from inside its own territory. None of NATO’s land-based missiles in Europe could reach beyond Eastern Europe into the USSR itself and the few nuclear-capable aircraft possessed by the Alliance, even if of just sufficient range, could not confidently count on penetration. There were, it is true, 400-odd Poseidon SLBM warheads assigned to the Supreme Allied Commander Europe (SACEUR), but the use of any of these would be likely to invite Soviet attack on the continental United States itself, while attack by ICBM from the US, of course, would be certain to do so.

European concern over the imbalance in theatre nuclear capabilities led to NATO’s decision in December 1979 to install on the territory of European allies, through the next decade, 572 American missiles of greater range and accuracy than those at that time available. Thus 108 Pershing II intermediate-range ballistic missiles would replace the Pershing I-A stationed in Germany, giving about 1,000 miles more range and, with their terminal radar guidance system, far greater accuracy. At the same time, 464 ground-launched cruise missiles (GLCM) would be installed, with a range of some 1,500 miles and a highly accurate terrain contour-matching guidance system known as TERCOM. Of these, 160 would be located in the UK, 96 in the Federal Republic of Germany, 48 each in Belgium and the Netherlands, and 112 in Italy. This decision, unanimously arrived at in the NATO Council, was accompanied by a proposal to negotiate with the USSR for the reduction of theatre nuclear systems. The deployment decision and the arms control proposal were seen as one package.

To the West the installation of these modernized weapons would do no more than correct a critical imbalance. To the Soviet Union, however, as Brezhnev had already warned, in an unsuccessful effort in October 1979 to avert the impending NATO decision, it was clearly seen as an attempt to change the strategic balance in Europe and give the West a decisive superiority. This would lie in affording the USA an option not hitherto available of attack upon the Soviet homeland (always an interest of paramount importance for the USSR) without using central strategic forces and so inviting attack on the American continent.

An immediate offer to halt the deployment of SS-20s would have cut the ground from under NATO’s feet. They were already being installed and would reach a total of some 250 by mid-1981, with a final total of 300 in 1982. Since in Soviet eyes this did no more than improve the effectiveness of an already established policy, no need was seen to depart from it and the offer was not made. The SS-20, the argument ran, was only replacing less efficient SS-4 and 5, with a greater range which would, as a bonus, enable all China to be targeted from inside the Soviet Union as well. The NATO move, however, was seen by the Soviet Union as a new and threatening departure, even though none of the modernized missiles would be ready before 1983 at the earliest.
