Well, with the administration(s) that Greece has, they will very seldom (if at all) allow the Greek pilots to push that little button in the middle of the stick. On the few occasions they were allowed to, the opponent was soundly defeated. Therefore, why not push the opponent to the limits of his aircraft and take advantage of the fact that eventually his aircraft will suffer such damage that it will make the aircraft prone to failure? No diplomatic incident, plus we save up on missiles.
Anyway, it's called using a strategic advantage. Turkey has done that by threatening with their numbers and their population. If the turkish army were to fight one vs one,
then Turkey would have the right to complain about "fair play".
Now, Erdogan has helped Greece in two ways, first of all he managed to remove his most competent pilots, and secondly he managed to create a shortage of spare parts for the turkish air force. Sometimes I wonder if he's really an agent working for Greece, but I don't believe that the Greek secret service has such competent agents.
Now, to our American friends, this is the part where I say "I told you so". I just love it when I get to say that. NATO should break Turkey in three independent states. One should be Constantinople (and perhaps the Aegean coast, under international/western control), the second should be a Kurdish state (SE Turkey, allied to the US) and the third should be Central minor asia (geopolitically irrelevant).
