From BBC World Service:
“The major arms that Saudi Arabia buys come from the US and UK. Its air force comes from primarily the US, F-15s and F-16s, but it has also purchased a large number of typhoons. The UK is a main participant in the manufacture and sale of the typhoon. It also supplies training to Saudi forces.”
Other comments on the main enablers of the war: the US and UK have helped with refueling of Saudi bombers, reinforcing the naval blockade, and under Obama the US only pulled back symbolically while still providing support.Embed from Getty Images
