This week's question time was inevitably dominated by the war in Iraq.

But eyes were focused particularly on the post-war situation and who would run the country, and for how long.

Both Tory leader Iain Duncan Smith and the Liberal Democrat's Charles Kennedy asked the prime minister what roles the US and UN would have in the post-war administration.

The Commons clash prompted an unusually large number of comments from users, with the majority expressing serious concerns about the future for Iraq.

Darren, from the UK, expressed a widely held view.

He said: " What is becoming increasingly clear is that the Americans will do whatever they want, regardless of world opinion.

"It is also clear that at some point Mr Blair is going to have to stop saying Yes to Mr Bush; as time goes by that is going to become harder for him to do.

However, this coming argument will give Mr Blair the excuse he needs to withdraw UK troops from Iraq."

And Karen J, an ex-pat living in the US, said: "The US has already started awarding post conflict rebuilding contracts to its cronies e.g. Haliburton (Dick Cheney's former company).

"It's about time Tony Blair woke up and realized that Bush is for Bush and doesn't give a rats what anyone else in the world thinks.

" This war is for Bush and his business friends to prop up their declining company profits. And remember, if you don't support Bush or the US you will have sanctions imposed on you.

"And they call this democracy, it is only democracy if you agree with the US."

There was praise for Mr Duncan Smith from Jim Davis in the UK.

"We have to credit Ian Duncan Smith for raising this issue of whether the UN or US rebuilds Iraq. This is constructive opposition - asking poignant and valuable questions."

But Ralph Lovesy from the UK attacked the two main political leaders and praised Mr Kennedy instead.

"The only leader with the courage to stand up for the British people in criticising the US is Charles Kennedy. If only he were prime minister, we wouldn't be in this unholy mess."

Mary K from the USA put the other view, stating: "Since the U.N. was paralyzed when it came to endorsing the action, the only countries whose opinions matter should be the ones willing to risk the blood of their nation's youth, primarily the United States and United Kingdom.

"I still believe the U.N. is relevant, but the bystanders to solving the world's problems should be left to a less significant role.
