PARIS (AP) An America eager to punish Iraq finds itself in heated conflict with European leaders who warn that war brings incalculable risk and must be only a final, desperate choice. They say a long history of war and terrorism on their doorstep has made them far more realistic about what can happen when diplomacy gives way to gunfire. Europeans, whose Middle Eastern experience goes back to the Crusades and whose economies are linked closely to Muslim countries just across the Mediterranean, believe the stakes for them are higher. They fear the consequences of a destabilized Iraq in a tough neighborhood, along with an unpredictable anti-Western backlash that could ripple through Muslim communities in their midst.
