After the war, an embargo was put on Spain by NATO as Franco was the only Dictator left in Western Europe. thousands of people died in Andalusia and it was only the intervention of the Perons that saved lives. Argentina had no money, but they sent beef which could be sold as it was not Spanish produce. Hence their support for the Argentinians in the Falklands War. Franco, in 1950 had the plan to send young Spanish males to work in the US and UK as labourers and waiters etc. so they could send Sterling and dollars home to help the Spanish economy. It worked! Then tourism took over in the late 50's early 60's and the rest, they say, is history!
