Spiralling in/out - puts the aircraft in the same place in a predictable pattern but makes you feel as though you're doing something. Area to 'sanitize' (as our US bretheren say) to make this effective includes a proportion of Bagdad city. (Not a secret, numbers are in Janes.) Make that secure and we can all go home!
Stop flying, can't get aid/trade/resupply in and out and the whole country suffers, which you may say is the purpose of those doing the shooting.
But, fly in/out without defensive aids - you gotta be joking! I go, but I don't volunteer.
