The kingdom spends 8% of its GDP on the military (highest in the world after Oman), which places it as the world's third biggest military spender behind the United States and China, and the world's largest arms importer from 2015 to 2019, receiving half of all the US arms exports to the Middle East. According to the BICC, Saudi Arabia is the 28th most militarized country in the world and enjoys the region's best military equipment qualitatively, after Israel. By the late 2010s, there have been continual calls for halting of arms sales to Saudi Arabia, mainly due to alleged war crimes in Yemen and especially following the assassination of Jamal Khashoggi. The state has attracted criticism for a variety of reasons, including its role in the Yemeni Civil War, alleged sponsorship of Islamic terrorism and its poor human rights record, which has been characterized by the excessive and often extrajudicial use of capital punishment, failure to adopt adequate measures against human trafficking, state-sponsored discrimination against religious minorities and atheists, and antisemitism, and its strict interpretation of Sharia law.
