But there are also consequences of "stop the war".

If I took that advice, and did not insist on disarmament, yes, there would be no war. But there would still be Saddam. Many of the people marching will say they hate Saddam. But the consequences of taking their advice is that he stays in charge of Iraq, ruling the Iraqi people. A country that in 1978, the year before he seized power, was richer than Malaysia or Portugal. A country where today, 135 out of every 1000 Iraqi children die before the age of five - 70% of these deaths are from diarrhoea and respiratory infections that are easily preventable. Where almost a third of children born in the centre and south of Iraq have chronic malnutrition.

Where 60% of the people depend on Food Aid.

Where half the population of rural areas have no safe water.

Where every year and now, as we speak, tens of thousands of political prisoners languish in appalling conditions in Saddam's jails and are routinely executed.

Where in the past 15 years over 150,000 Shia Moslems in Southern Iraq and Moslem Kurds in Northern Iraq have been butchered; with up to four million Iraqis in exile round the world, including 350,000 now in Britain.

This isn't a regime with Weapons of Mass Destruction that is otherwise benign. This is a regime that contravenes every single principle or value anyone of our politics believes in.
