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.
Enlighten me.
Leopold's Congo was so horrifying that when he gave up personally ruling it and let it be turned into "just" an ordinary colony where the colonizing government and its companies worked hand-in-glove to ruthlessly exploit the place at the expense of the locals... that was actually better than it had been under Leopold's direct rule. Under personal rule by Leopold, estimates of the death toll in the Congo range at least into the millions and possibly over ten million.
That and an impression that Iran “wants to do bad things” (like human rights violations and irresponsible ownership of nuclear weapons), and doesn’t like world powers keeping those plans at bay.
It's also instructive to pay attention to the names. Some of them are going to jump out at you, and at least a couple times you're going to think "wait, isn't he the bad guy" when, once upon a time, some recognizable name was "on our side" (but really was on his own side all along, and willing to play at doing a major power's bidding in order to get funded/armed/maintained in power/etc.).
And some of the names of the foreign-policy wonks are going to get eerily repetitive, and you'll wonder how these guys managed to stay cozy with administration after administration despite their track record of literally leaving desolation around the world. Worse: you're going to read their bios and find out some of them are still in positions of power and being taken seriously today.
