Doesn't one see the terrorists are losing their war against the invaders (US)and received no help from God?

In Iraq the resistance from the terrorists against the US army seem to be losing and they seem to have no help from their God they call great. If this situation continues, once should doubt whether the resistance carried out is right. For any death of the enemies some or many of their own countrymen suffer death or injuries. Even the US people themselves through their political system cannot succeed to get pullout. How long can the Iraqi people suffer. Is God on their side? If it is so, then the terrorists should be now fighting in the open. How would God allow them to fight like cowards to commit killing indiscrimately?
