The latest news from the Chilcot Inquiry into the Iraq war make depressing reading. Geoff Hoon's revelation that Gordon Brown blocked funding for helicopters and the news that Tony Blair delayed preparations for the war for months in order to pretend that the decision to invade had yet to be finalised is appalling.
Whatever the rights and wrongs of going to war, and I believe the case for removing Saddam was persuasive, there can be no justification for going to war knowingly unprepared. Blair always seemed to like being hailed as an international statesman by committing British troops to action but was unwilling to make the political sacrifice of confronting his Chancellor in order to secure the funds to pay for it.
There is no justification for going to war incompetently and this is the real reason why the war has become so unpopular not the arguments about the legality. The public were largely supportive of the war when Baghdad fell to the allies and previous wars of similar legal status have been generally supported if they are successful.
Most of the above also applies in spadesto the inept American handling of the invasion too, at least under the mismanagement of Donald Rumsfeld.
