They believed the United States should not start a war against a nation that had not attacked the United States.
Step-by-step explanation:
The world demonstrations against the invasion of Iraq in 2003 were a series of protests called and coordinated worldwide against the imminent invasion of Iraq by the United States and its allies, being the first calls of a truly global character in history.
These massive demonstrations were organized mainly by anti-war and anti-war organizations, many of which had already opposed the invasion of Afghanistan years ago. In some Arab countries, the demonstrations were organized by the State; However, Europe witnessed the largest demonstrations, including the three million people who marched through Rome, capital of Italy, against the war, a manifestation that entered the Guinness Book of Records as the largest anti-war demonstration in history. According to the French academic Dominique Reynié, in just three months, between January 3 and April 12, 2003, 36 million people from around the world participated in nearly 3000 protests against the Iraq war. After the demonstrations of February 15, 2003, the most numerous, the writer of the New York Times, Patrick Tyler, said that "it had been demonstrated that there were two superpowers on the planet: the United States and world public opinion."
In the United States, pro-war protesters often described opponents of war as "a minority"; A Gallup poll on September 14, 2007 showed that "since the summer of 2005, opponents of the war outnumber their supporters. Most Americans believe that the war was a mistake. " In Europe, surveys of the time showed that between 75 and 90% of the continent's population opposed war. Local circumstances allowed the effects of the protests to endure over time, especially in the United Kingdom, the United States, Spain and Italy. In spite of everything, the alliance initiated the invasion of Iraq on March 20, 2003.
