So much of the turmoil and violence around the world today is fallout from meddling by western powers over the last couple centuries. Want to understand the modern middle east? Got to dig into the US overthrow of Iran's government, the background of the British rise to prominence (WWI and the Sykes-Picot agreement), etc. Want to understand trouble in just about any part of Africa? Dig back to what the European colonizers did to the place, and hoo boy wait till you learn the truth about Belgium.
You really cannot even begin to pretend to have a hint of a grasp on modern world politics and conflicts without understanding this stuff.
