Why a UAE arms embargo needs route-level evidence

What are the pros and cons of the United Kingdom imposing a total arms embargo on the UAE until peace is achieved in Sudan?

Its value cannot be judged without tracing the actual deals and supply routes, because the UAE may be a visible flash point rather than the main source of weapons reaching Sudan.

A firm assessment requires checking the actual arms deals and how much reaches Sudan through the UAE. Weapons can move through intermediaries and other routes, making a single visible state an uncertain guide to the supply network. Alex Clarke's tentative reading is that the UAE may not be the principal route and that other powers are involved higher in the chain. He stresses that this view rests on information he has heard and could be wrong because he has not investigated the subject in sufficient depth.
