Papa Doc will in the end do nothing. What can he do? He is a little man who is very lucky, his EOKA record is still on file, to be the president of a little country, which has little or no effect on world events. He is just posturing for the forthcoming elections.
If he shouts loud enough the British government may just close the bases down. Now the British taxpayer would be most grateful for that. Bases not really needed now. The Americans have opened so many new ones in former Soviet territories such as Poland etc. And of course the American basis in Turkey. The losers of course would the the GC's who work at the bases; and those that derive a living from the tourist industry; three million British tourists???? but Papa Doc couldn't care less about them.
Grow up Mr President or resign and let somebody younger take over who could lead Cyprus into the 21st century.
