As the fourth anniversary of the Iraq approaches, new concerns are being raised over the effect the war has had on global security. A new study by Mother Jones magazine has found that the number of fatal terrorist attacks has increased by over 600 percent since the U.S. invaded Iraq. The effect of the Iraq war has been felt from London to Kabul, and from Madrid to the Red Sea. The study contradicts key claims by President Bush that the Iraq war has made the world safer.
