I would sell them this if you look L G Bs have been around for a long time . I worked with them , loaded them on aircraft , back in the 70s and they had been around for awhile then . However I would not sell them a missile defense system which could eliminate the threat of their aircraft ever reaching the target . Not to mention our birds taking theirs out . If you sell them the weapons you know what they have and can plan counter moves knowing the limitations . Just an old weapons systems tech view
