Come midnight tomorrow the U.S. will unilaterally lift thearms embargo against the Muslim-led Bosnian governmentin an effort to cut the Serbs' 6-to-1 weapons advantage. The Clinton administration is complying with a mandate from Congress, which voted last summer to cut off all funds for enforcing the embargo by Nov. 15 if the Bosnian Serbs don't agree to a peace plan. But U.S. European allies disagree with Clinton, arguing that additional weapons endanger their peacekeeping troops. The seemingly dramatic move by the U.S. will have little effect on the conflict, says TIME Central Europe Bureau Chief James Graff. The reason? The Bosnians have, of late, turned around their war effort by capitalizing on arms obtained through third parties like their Croat allies. In fact, Bosnian sources tell Graff that "they've even been practicing using U.S.-made shoulder-launched anti-tank weapons." The immediate ramification isn't military -- it's political: Once again the U.S. is leaning on the Serbs to get in line and accept peace terms, Graff says.But the message seemed lost today as Serb forces bombed southwest Bosnia, raining mortar shells on a Roman Catholic Church as 50 children attended catechism, killing one child and wounding six others.Post your opinion on theInternationalbulletin board.
