Relations across the Atlantic are souring again. After discovering CIA agents snooping on economic targets, the French welcomed Cuban leader Fidel Castro to Paris. Officially, there was no linkage between the two events, but Castro's red carpet reception seemed designed to irritate Washington. Similarly, President Clinton's strained relations with the British government, which attempted to dig up campaign dirt on his days at Oxford, took a turn for the worse when Clinton allowed Sinn Fein leader Gerry Adams to make an official, fund-raising visit to the U.S. Cries of rage were heard in Whitehall. All this is unfolding against a backdrop of deepening differences over Bosnian peacekeeping, NATO expansion, and dealing with Iran and Iraq.
