Lots of the kit involved in this conflict is very old, and some of the kit is a lot older than the Iranian F4s are.
Just ask yourself a few questions:
Were the Iranian F4 missions succesful?
Should the Turks give up their F4s on your say so? While an F4 was lost recently (with the loss of crew QUALIFIED to fly) there is no reason that a more modern aircraft wouldn't have suffered the same fate doing the same mission.
I could say that IF and when you join up you may have to get used to working alongside forces whom will also have public plans to do you harm, but history should already have shown you that in war or conflict enemies can become uneasy friends and visa versa.
Holding a grudge just isn't always an option when politicians are involved, and just as Iran may say things against the West publicly the USA also had detailed plans to invade Canada not that long ago !!
