Travis McGee might call it the Case of the Busted Flush. President Alyaksandr Lukashenka last month forced diplomats in Minsk to evacuate their residential compound, ostensibly to allow workmen to fix the plumbing. In retaliation, the countries of the European Union, joined by the United States and several other Western countries, have announced that entry visas will not be granted to Lukashenka or other senior Belarusan officials. … Poland agreed last week to operation of a “Radio Free Belarus” from a transmitter on its territory. The United States and the European Union will finance the broadcasts.
