Good. I do not believe in "equitable" response. I believe in "totally over the top, OMG, beat the shit out of your opponent" response. Rain the destruction of a thousand arsenals upon their heads, take the ground, enslave their women and children for two generations, destroy their abominations of worship. Forcefully convert them to Christianity and from day one, make them fear, I mean really, viscerally FEAR the word crusade.
The problem with modern warfare is that we have taken the fear out of going to war. We fight till one side decides they need a break. We need to restore the fear that you will lose your wifes, daughters, sons, and your culture and history should you dare to start a war. Then, and only then, will politicians understand the costs of being a fool.
When men behave like animals, there are only two choices. Offer the hand of friendship should they opt to change their ways. When that is rejected, beat them into submission.
