So far all I’ve seen in the English-language press is a denial by a NATO official that it was discussed. But according to Nicolas Gros-Verheyde at the Bruxelles 2 blog,a Greek military office cited by the Bulgarian press claims that theU.S. is considering basing part of its anti-missile system in Bulgaria.That’s a long way for a rumor to travel, but Bulgaria has expressed interest in the idea before.
