RANKED: The least peaceful countries in the world

North Korea - the country that recently said it's considering a plan to fire nuclear-capable missiles at Guam - is one of the least peaceful countries in the world.

That's according to the 2017 Global Peace Index from the Institute for Economics and Peace (IEP), which analyzes 162 nations and ranks them on their levels of peacefulness every year.

To compile the ranking, the IEP looked at 23 indicators, like violent demonstrations and weapons imports, across three categories: the level of societal safety and security, the extent of ongoing domestic and international conflict, and the degree of militarization. Collectively, the countries included make up 99.7% of the world's population.

Overall, the world became more peaceful in 2017 compared to 2016. In the past year, 93 countries became more peaceful, while 68 countries became less peaceful, according to the index.

The ones that ranked lowest, with the least peaceful country at #1, are below.
