The visualization below sums up the global weapons trade during the Obama era, minus data from 2016.
It was created by data scientist Hai Nguyen Mau, and each relationship plots the value of the weapons trade between two countries based on data from SIPRI.
It’s important to note that while this data includes major weaponry transfers such as tanks, jets, missiles, and ships, it excludes guns and ammunition or military aid. Lastly, the thickness of each line represents the total value of each trade relationship, while the proximity of two linked countries shows how close each relationship is. (i.e. if a country only imports from Russia, they will be much closer to Russia than the U.S.)
Together, the United States, European Union, and Russia combine for over 80% of weapons exports, while the rest of the world fills out the “longtail” of the exporter distribution.
From the perspective of imports, the field is much more equal because almost every country aims to spend at least some money on defense. India is the largest importer of weapons in the world with a 14% share of the market.
