Ron Paul changed American politics in a way that no single individual can claim: it was Paul, a congressman from a rural district in Texas, who put libertarianism on the political map. It was the movement he inspired – a movement driven largely by young people – that has challenged the War Party like no other. Not even the antiwar movement of the 1960s has done so much to change the American consciousness when it comes to our interventionist foreign policy – and Paul's new book, Swords Into Plowshares: A Life in Wartime and a Future of Peace and Prosperity, encapsulates the spirit of the man and the seed he has planted.
