Erdogan himself spoke about the supply of F16 in his speeches. He demanded upgrades and new purchases to the f16s and also demanded that Turkey be included back in the f35 plan.

did the us try to buy the s400s from him? You even distort the events that are going on in my own country. dumb.

The s400s are a crappy air defense system. turkey didn't even install the S400s it bought.
