29% of global arms exported by the U.S.

"The five largest suppliers of major weapons during the five-year period 2009–13 were the United States (29 per cent of global arms exports), Russia (27 per cent), Germany (7 per cent), China (6 per cent) and France (5 per cent). These top 5 suppliers accounted for 74 per cent of the total volume of arms exports worldwide. The USA and Russia together accounted for 56 per cent of the volume of arms exports." (thanks Amir)
