The war is not coming. The war has arrived. We are currently fighting the first long campaigns. The later greater campaigns will follow ineluctably if we do not use sufficient force amd speed to excise the enemy's heart. Hearts and minds and nation-building is a losing proposition that is protein-rich fare for the main enemy who is not in Iraq but a little east.
The final battle between good and evil is in god's hands. Hold fast to what is right and you'll win through.
