Now for the pessimist .02.
One religion exhorts its followers to love the enemy and turn the other cheek. Another religion exhorts its followers to fight, enslave and slaughter the other wherever he be found.
You don’t need much game theory for the outcome.
The difference is that the “Commander-in-Chief” is coming to personally take care of business. One group has an earthly perspective and thus fights with the weapons of the world, the other has an eternal perspective and thus waits on the King of Kings to vanquish the foe by the breath of His mouth.
As He powerfully spoke in the beginning, He shall again.
But when a Christian sees a great wrong, if we follow the actions of Jesus, we can act with aggression. The story of the money changers in the temple show this.
Christianity has a long history of creating factions that favor collectivist social change; “Liberation Theology” is only one the latest. Christians (occasionally including influential American Christians) have been involved in union movements, movements calling for various kinds of government programs intended to improve the welfare or prospects of various portions of the population, and many similar efforts.
And it doesn’t help to claim that these people are not “True Christians” - they define themselves as such, and God has not seen fit to provide an unambiguous method of separating the “true” from the “untrue”, instead leaving the task to fallible humans. For example within my lifetime Christian supporters of civil rights for black Americans were frequently referred to by other Christian Americans as “communists” bent on subverting “the American way of life” because they opposed government mandated racial segregation.
That’s why we have the old Testement/Eye for an Eye/Jewish buffer. It this case, I can swing both ways.
But it's not a game. Man plays games, God rules. Once man realizes that and starts to live that truth, then and only then will there be peace -- individual and universal.
I’d also point out that when Christ selected “the rock” upon which His church would be built, he didn’t pick the devout, mild-mannered apostle whose faith was unshakeable (St. John) . . . He picked the impulsive, aggressive guy who would deny Christ three times, and didn’t hesitate to draw a sword and cut off the ear of the high priest’s servant when they came to arrest Him.
Pan-islamists must be killed en masse.
How many muslims are islamist?
But see Luke 22:36-38. See also Revelation 19:11-21.
