I don’t know about the F-16s.The range of the initial variants would have been very poor to even get to Armenia or Azerbaijan,which were the nearest Republics.The F-4 could do that(Israel had them in the 70s itself) with a small payload,one way -the F-15 could as well.Ballistic missiles are another issue.
My briefer said it was one way. I may be mistaken about the F-16.
