Colombia produces more cocaine than any other country. Sadly, that’s the only thing most people know about the country. Locals would rather that Colombia was known for its green energy (which produces more than 70% of the country’s energy needs), its world-class mines, or its bird life—it has more species than any other nation. But mention Colombia and people think drugs. How did Colombia get the depressing distinction of being the world’s leading producer of cocaine?

An archive of news stories on any country will be mixed—some happy, some sad. Congo, or the Democratic Republic of Congo to give the country its full name, might be the exception. Despite its extraordinary natural resources, including large deposits of diamonds, copper, uranium, and coltan, and enough hydro-electric potential to power all the countries of Africa South of its borders, the news out of Congo has been reliably tragic for more than a hundred years. If you replace “Despite” with “Because of” at the start of the previous sentence, you’ll have the main reason why Congo has been a mess for so long.

Public protests against governments are common. But it’s unusual when a neighbouring country takes advantage of the protests and invades. That’s what happened to Ukraine in 2014, when demonstrations in the capital city of Kiev prompted Russia to attack. Within weeks, Russian soldiers seized thousands of square miles of Ukrainian territory, including the strategic Crimean peninsula. They are still there. Ukraine’s government is no longer sovereign over all of Ukraine. How did this happen?
