Hanoijane,
Your RPG philosophy has got to be the worst explanation in order to counter the need for aircraft in a war zone ever. To follow your logic, the rebels would of course demonstrate far greater zeal and commitment to the cause if they endeavoured to get within arms length of their opponents and throttle them. No need for guns either then.
The reason the aircraft are there at all, is because the rebellion against the mad duck (Gadaffi Duck, geddit
) would be over by now and some rather spiteful and begrudging reprisals brought to bear on the survivors, if it wasn't for the "just in the nick of time" arrival of air to ground ordinance.
There is a little more to this than demonstrating one's ardour and passion and willingness to suffer all for the cause!
