I don't agree, they have everything to lose. Their country AND their lives. That's the reason why they put up a good fight.
And their use of guerilla tactics, well.... what would you do when you don't have an airforce, and face an opponent with superior firepower ? This is their only chance, an open fight is not an option for them. In the last gulfwar they lost 20.000 armoured vehicles in 100 hours. They've learned their lesson.
