Fair comment re: refugees, however, your comment implies that being displaced within your own country isn't as bad as crossing a border into another country - not sure if that was the intention?

The small print provides a little bit more clarity on the Syria figures: "Syria data only includes people displaced during years of direct U.S. military involvement in the war and in five provinces where U.S. forces have fought."

Even if the U.S. military hasn't directly caused every single one of those displacements, and I appreciate that it's impossible to put an exact figure on these things, it's a decent yardstick which shows that wars involving just one nation has caused at least half of the world's displaced people and refugees. Shouldn't a nation with a defence budget larger than most countries' GDP and the most high-tech weaponry on the planet be a little better at avoiding civilian targets? Shouldn't a country that sees itself as the most civilised nation on the planet be a little more concerned about involving civilians in conflict?
