Pattern? This civil war wouldn’t have been won by the revolutionaries without support from NATO but there still would have been a civil war. This civil war was not faked by NATO, it was very real – and all things considered the right side won.
It would make more sense for Nato to attack Saudi/UAE/Bahrain etc.
They buy western hardware so if we destroy a few hundred Tornadoes/Eurofighters/F16s then there are big replacement contracts to create jobs in Europe and America.
We spend $8Bn on some new stealth fighters.
We only ever use them against countries with no air defences. So the fighters never get 'used up' so there are massive job losses at BAe.
The traditional option was to fight a competent enemy - but then your own people get shot down which doesn't play well with the electorate.
A modern solution is to sell your weapons to an ally, then destroy them and then sell more of the same replacement items to the replacement government. The big advantage of that is that the replacement government is normally pretty well disposed to you - if they know whats good for them.
