The British government didn’t do such a thing. It was a privat company Baykar was buying parts from. Private companies can decide who they sell and who they don’t sell to. The British government can’t dictate it. There are no sanctions or Embargos by the British government against Turkey. Quite the contrary, Britain has been one of Turkey’s biggest supporters behind closed doors for a long time now. As it is aware of Turkeys importance in NATO and for Europe’s security.
Please learn to differentiate between Governments and private companies.
As an example Germany’s government has embargoed products by vetoeing the sale of military products such as tank engines.
Britain on the other hand has not done such a thing but instead of private company based on Britain has decided on its own to suspend business with Baykal another private company.
That will not change a thing, if they manage to winn the public and they demand ther goverment. Every defence cooperation will be always on a thing ice. A Private company, doesn't that say much to you? What will happen when next Karabag war breaks out? Will the British show us ther other half?
Ther is no guarantee.
