A day after US President Bush paid a surprise visit to Baghdad, US senator Hillary Clinton, accompanied by fellow senator Jack Reid, visited Iraq to see US troops in the country and meet people involved in reconstruction and humanitarian work. Clinton spoke of the importance of the international community working together to rebuild Iraq, adding that she believed that the UN should have a greater role in the post-war effort. 'I am a big believer that we ought to internationalise this [operation], but it will take a big change in our administration's thinking,' she told reporters. Clinton said that the toppling of former president Saddam Hussein's regime was a long-term operation, and would involve more than just military might. 'What is important from our experience in the Balkans and our experience now in Iraq is that it's no longer enough for our military, the most powerful in the history of the world, to win the battle - they have to also win the war for hearts and minds.'
