No, the Italians don't hate us. Their print media is a reflection of their intense objection to Bush's foreign policy. To their credit, the Italians have never forgotten the horrors of war, and for that reason they will never support pre-emptive, unprovoked war.
Ironically, the French and Germans were absolutely right to object to the Iraq war based on the reasons given for the strike, ie WMD, mushroom clouds, and mobile bio-weapons factories.
