No. That is not the answer.
Overwhelming force, complete destruction of the enemy's capacity to wage war, total victory, unconditional surrender, military government, gradual return of power to the defeated (and now reformed) enemy under a representative form of government based on the principles of liberal democracy. Oh, and severe punishment of neighbors -- e.g., Syria, Iran -- for interfering.
It worked well in WWII, and would work in Iraq. We're using the Korean War & Vietnam War models, both failures. Time to use a successful strategy.
