I thought Saudi Arabia used Challengers I guess I'm either wrong or they have enough money for both .
As for Iraq I might be being a little cynical but it reminds me a little of when America sold Iran F14's but I suspect America just wants rid of them
now they are outdated.
I woulld think whatever we sell them, we also have the easy capacity to take out as well. They apparently need some typ of military hardware and
someone is going to sell it to them anyway. No doubt these will also end up in Iran in some way also. What better technology for them to have than
ones we can test on to destroy here. (which I'm sure we already have)
