Well I disagree. Post-WW2, Britain was very much in the political and economic backwaters. Empire gone, Commonwealth (relevance - historical connections that is all?). Germany, France, Japan, USSR were far more important in world politics than Britain until the 80s. In 1979 Britain had gone to the dogs - weak politicians, economy in a big hole (much like today). Thatcher put Britain back on the World stage for the first time in decades. I didn't agree with everything she did, but I don't know how anyone can deny the importance of her role in raising Britain's role on the international stage. Opinions and all that.
she certainly had some great mates on the world stage,general Pinochet and saddam hussain being two of them.
