our own, the cession of national territory and the transfer of populations that inhabit them to foreign sovereigns," said Salazar. He went on to state that the UN's failure to halt aggression against Portugal, showed that effective power in the U.N. had passed to the Communist and Afro-Asian countries. Salazar also accused Britain of delaying for a week her reply to Portugal's request to be allowed the use of certain airfields. "Had it not been for this delay," he said, "we should certainly have found alternative routes and we could have rushed to India reinforcements in men and material for a sustained defence of the territory." Hinting that Portugal would yet be vindicated, Salazar went on to state that "difficulties will arise for both sides when the programme of the Indianization of Goa begins to clash with its inherent culture ... It is therefore to be expected that many Goans will wish to escape to Portugal from the inevitable consequences of the invasion." In the months after the conflict, the Portuguese Government used broadcasts on Emissora Nacional, the Portuguese national radio station, to urge Goans to resist and oppose the Indian administration. An effort was made to create clandestine resistance movements in Goa, and within Goan diaspora communities across the world to use general resistance and armed rebellion to weaken the Indian presence in Goa. The campaign had the full support of the Portuguese government with the ministries of defence, foreign affairs, army, navy and finance involved. A plan was chalked out called the 'Plano Gralha' covering Goa, Daman and Diu, which called for paralysing port operations at Mormugao and Bombay by planting bombs in some of the ships anchored at the ports. On 20 June 1964, Casimiro Monteiro, a Portuguese PIDE agent of Goan descent, along with Ismail Dias, a Goan settled in Portugal, executed a series of bombings in Goa. Relations between India and Portugal thawed only in 1974, when, following an anti-colonial military coup d'état and the fall of the authoritarian rule in Lisbon, Goa was finally recognised as part of India, and steps were taken to re-establish diplomatic relations with India. On 31 December 1974, a treaty was signed between India and Portugal with the Portuguese recognising full sovereignty of India over Goa, Daman, Diu, Dadra and Nagar Haveli. In 1992, Portuguese President Mário Soares became the first Portuguese head of state to visit Goa after
