Timetable: Next steps on Iraq
After nearly two months of diplomatic wrangling, the United States has won UN approval to force Saddam Hussein to disarm or face "serious consequences" that analysts say would almost certainly mean war.
A UN Security Council resolution gives a timeframe of up to 15 weeks for a final verdict on whether or not the Iraqi leader is developing weapons of mass destruction and ballistic missiles.
While the resolution has removed any automatic resort to force against Iraq, if Baghdad is deemed to have impeded the work of UN arms inspectors, Washington would not have to wait for UN approval before taking military action.
The timetable according to the resolution:
If weapons inspectors find that Iraq has failed to cooperate with their work, then the US would discuss the consequences with Security Council members, but would not have to wait for another UN resolution before taking military action.
The US would have to take into account if any debate with members of the Security Council lasted too long, conditions for troops in Iraq would begin to become dangerous.
According to GlobalSecurity.org temperatures in the Iraqi desert will begin to heat up by March. In July and August, the average temperature is higher than 48 degrees Celsius (120 degrees Fahrenheit).
Troops will have to be dressed in chemical protection gear the whole time, which will become unbearably hot.
Also, April marks the beginning of Iraq's windy season, when sandstorms would severely reduce air operations.
The weather would not cool down again until October.
