Imagine: Everyday thousands of people get killed in a war no-one asked for. Friends and family are send to a horrible place with little chance you’ll ever see them again. This war, a useless and disgusting war started without any reasons and only goes on because the leaders of your country are too proud to make it end. For millions of American citizens this nightmare became truth. In 1964 the American president Johnson started sending soldiers to Vietnam. At the end of the war in 1972, it is estimated that, in total, over 2,5 million people on both sides were killed.

This song was written in 1962, when the war had not yet started, but was used, a couple years later, as a protest song against the war. â€Å"Blowin’ in the Wind† starts with a couple of questions: How many roads must a man walk down Before you call him a man? Yes, n how many seas must a white dove sail Before she sleeps in the sand? Yes, n how many times must the cannon balls fly Before theyre forever banned?

The rest of the song is alike: the last question is a question that attacks the government and the answer stays the same (The answer, my friend, is blowin in the wind, The answer is blowin in the wind.) With this song Bob Dylan wants the government to realize that they are acting nuts. With rhetorical questions he tries to send his message, his call for freedom, to the president and his followers.
