WHEN a politically-besieged President Bill Clinton launched punishing air strikes against Iraq late last Wednesday, only hours after United Nations military inspectors declared that their work in Iraq had been blocked, his action created an extraordinary nexus of military and political uncertainty in Washington. Clinton, who ordered the attack—code-named 'Desert Fox'—in coordination with the UK, pre-empted any intervention by the UN Security Council in an apparently calculated move. The air strikes are the largest the US has undertaken since the 1991 Gulf War.
