Was Jesus really a pacifist?

Jesus is perceived by many as being a pacifist who never practiced or advocated violence of any kind.  He commanded us to turn the other cheek when someone hits us and to love everyone, including our enemies.  On the basis of these commands some Christians have concluded that a Christian must never engage in any kind of violence.  They believe it is wrong for a Christian to serve in the military, even if his country is at war.

If we consider only these teachings of Jesus this seems to be a logical conclusion.  But Jesus also did and said some things that are inconsistent with pacifism.
