It seemed clear that Bush had made up his mind to take military action, even if the timing was not yet decided. But the case was thin. Saddam was not threatening his neighbours, and his WMD capability was less than that of Libya, North Korea or Iran. We should work up a plan for an ultimatum to Saddam to allow back in the UN weapons inspectors. This would also help with the legal justification for the use of force. The Attorney-General said that the desire for regime change was not a legal base for military action. There were three possible legal bases: self-defence, humanitarian intervention, or UNSC authorisation. The first and second could not be the base in this case. Relying on UNSCR 1205 of three years ago would be difficult. The situation might of course change. The Prime Minister said that it would make a big difference politically and legally if Saddam refused to allow in the UN inspectors. Regime change and WMD were linked in the sense that it was the regime that was producing the WMD. There were different strategies for dealing with Libya and Iran. If the political context were right, people would support regime change. The two key issues were whether the military plan worked and whether we had the political strategy to give the military plan the space to work.
