Meanwhile, the Russian S-400s are expected to be delivered to Turkey by July 2019.
Guess we will see after this july then what happens.
Lets use logic.
What happens if we dont get the F-35s?
My country could kick out all US personnel and equipment out of our bases(incirlik).
NATO could lose the only Muslim country as a member.
The Black Sea would become hostile to NATO.
My country would leave Afghanistan(big deal,no Muslims,Taliban go ahead).
We could attack the SDF/YPG and take all their territories,no more US Airbases.
Invite Iran to the party but this time protected by the S-400(no more Israëli threat).
The impact on Israëli security would be immense.
All indigenous projects would get priority(TFX,engine projects,TF2000 etc).
Join the SCO.
Many more headache situations for the(to many) US.
Trump had to show his BFFs UAE and KSA that he is ''hurting'' Erdogan,thats all.
Not if but when we get them,he can say ''but i blocked them''.
Btw,you can change all the words 'could' to 'would'.
