As far as taking action is concerned 1441 is irrelevant. As I've pointed out, action is endorsed under previous resolutions. These are the basis for on-going attacks by UK and US forces. They been challenged by Iraq and proved valid.
Other nations may have their opinions Jacko, but the legality of the actions of US and UK has been upheld in practice. And it's equally applicable on a larger scale since the resolutions do not impose limits.
