Hans Blix is the man in charge of seeing if Iraq has weapons of mass destruction.
He gave his second report on Iraq to the United Nations on Friday.
The main points
In favour of Saddam Hussein, he said:
Iraq was giving more active help to weapons inspectors
American U2 spy planes were being allowed to fly over Iraq
Some Iraqi scientists were being allowed to talk to inspectors in private
Iraq was talking to South Africa, to get help on disarming
But against Saddam Hussein:
Iraq has some banned missiles (which can fly further than they should)
1,000 tonnes of nasty chemical weapons are missing
And they could still be more helpful to weapons inspectors
Mr Blix's statement started a big argument among the members of the UN Security Council listening to him speak.
France and Russia said it was encouraging, and the inspectors should be given more time.
But the US and UK didn't agree.
Later on, President Bush said that Saddam was still "deceiving the world".
The next crucial date is 1 March, Hans Blix's next report to the UN.
If Iraq continues to be more helpful, war could be delayed again.
If not, war could follow very soon.
