The United States had broken the Atropos code even before Japan’s all-conquering Fujitsu computer company signed a joint-venture agreement with America’s biggest computer company in 1984. Before General Seriy had received his decoded message, Lieutenant General Henry J. Irving, Chief of Staff of the Rapid Deployment Force (known to his friends as ‘Humdinger Hank’), had got his. Minuted General Irving: ‘It is clear from decoded messages that Cuban communist forces, while pretending to lie low, will attack US convoys with missiles and aircraft as soon as they put to sea, and that attacks (possibly with biological weapons, probably with nuclear and chemical) will start against Guantanamo at that delayed moment. It is essential that America’s non-nuclear war plan be launched against Cuba from this moment, well before the Cubans strike.’
The US plan was activated. From military airports in Florida, and from the decks of Atlantic Fleet carriers, attacks were made against military and industrial targets in Cuba, with devastating effect. The weight of the attack wholly overwhelmed the Cuban air defences and caused very many casualties. A total naval blockade was imposed, cutting Cuba off from the rest of the world. US forces (particularly Cuban émigrés and Filipino mercenaries) massed to invade the island.
The United States had not anticipated the reaction of the rest of Latin America. The Secretary-General of the OAS sent an urgent message to the US President on 10 August: ‘Although all my members are in principle on America’s side in its global confrontation with the Soviet Union, I must tell you that there is general opposition and revulsion among them against the possibility of the US killing more civilians in Cuba. The Cubans have not yet launched any warlike actions against you, but you are bombing them. I beseech you to send me an instant assurance that in no circumstances will American nuclear weapons be used against Cuba, and that civilian casualties there will be kept to a minimum.’
‘Humdinger Hank’ regarded this message as appalling impudence. Fortunately, the speed of events in Europe cooled his actions before invasion of Cuba could actually take place. On the day when it became evident that the Soviet Union was breaking up, Cuba’s Economics Minister minuted to the premier: ‘Our great Soviet ally has lost this war, so let us be as sensible as General Franco was when Hitler was defeated in 1945. We have an advantage that Franco did not have in a totally de-Nazified Europe in 1945. Many of our fellow Latin American countries are allies of the US, but they are not blind servants of US national interests. They will see the Soviet defeat as a mixed blessing. They will fear that the US, free from the limitations previously imposed by Soviet power, may try to gain rigid control over its Latin American area of influence. Previous fears of “subversion from the Soviet Union and Cuba” in Latin America may now be replaced by fear of US neo-colonialism.
‘In these next few critical days we should therefore tell our volunteer troops still fighting at the side of guerrillas on the Central American mainland to surrender to Latin American governments, asking perhaps for Mexican and Venezuelan protection. But we should not accept any US ultimatum for unconditional surrender by Cuba itself, and we should say that any US invasion of Cuba will be met by our armed forces fighting to the last man.’
This was agreed. Some of the remaining Cuban troops on the mainland were anyway isolated and running out of supplies. Most of them surrendered, coming in together with guerrilla troops through November 1985. Only small pockets of about platoon size still kept fighting, but no peace treaty had yet been signed between Cuba and the US.
The Secretary-General of the O AS sent another urgent telex to the US President in late November: ‘Let me be very frank. The Government and people of Cuba still expect an invasion from the victorious US. Nearly all my members think such an invasion would be a great mistake. Bluntly, I must give you a warning that will distress you. If you continue with an aggressive stance towards Cuba, then the Mexican (and possibly the Venezuelan) Presidents will fly to Havana to sign with Cuba a treaty of assistance for the provision of food and oil. In helping Cuba, countries such as Mexico and Venezuela will be protecting their own freedom of action.
‘It is believed among my members that the US is now confronted by both a great danger and a great opportunity. The danger is that the US, free from the limitations previously imposed by Soviet power, may try to encroach upon the independent policies of other American countries. The opportunity is that of creating a united Latin American front, including a tamed Cuba, willing to play a more assertive role in world affairs.’
