The head of Israeli intelligence said that the US invasion of Iraq would probably take place in early February. American and British personnel and equipment are on their way to the Persian Gulf that would put nearly a 100,000 troops in the area by the end of January. 

However, training of Iraqi exiles to assist US troops  doesn't begin until January. Several thousand volunteers have already been accepted and these bilingual men would be a big help in dealing with Iraqi civilians and troops. If the training course were short enough, and still effective, these Iraqi military translators/guides would be available for a February invasion.
