Mark Steyn makes the case for the invasion in The Spectator:

When Amr Moussa, secretary-general of the Arab League, warns the BBC that a US invasion of Iraq would ‘threaten the whole stability of the Middle East’, he’s missing the point: that’s the reason it’s such a great idea. Suppose we buy in to Moussa’s pitch and place stability above all other considerations. We get another 25 years of the Ayatollahs, another 35 years of the PLO and Hamas, another 40 years of the Baathists in Syria and Iraq, another 80 years of Saudi Wahabbism. What kind of Middle East are we likely to have at the end of all that? The region’s in the state it’s in because, uniquely in the non-democratic world, it’s too stable. It’s the stability of the cesspit.
