Howard ignored official advice on Iraq's weapons and chose war

Howard ignored official advice on Iraq's weapons and chose war: 

"The reason there was so much argument about the existence of such weapons before the war in Iraq 10 years ago was that to go to war on any other pretext would have been a breach of international law. As Howard said at the time: ''I couldn't justify on its own a military invasion of Iraq to change the regime. I've never advocated that. Central to the threat is Iraq's possession of chemical and biological weapons and its pursuit of nuclear capability."
So the question is what the government knew or was told about that capability and whether the government ''lied'' about the danger that Iraq posed. At the time, Howard and his ministers asserted that the threat to the world from Iraq's weapons of mass destruction was both great and immediate."
