Well, I would have been out of there years ago for one. But that's not what you're asking.
Pull troops out and use them to contain terrorists within Chechnya's borders, set up friendly government, arm them, and have them self-police (sound familiar?) then send in Special Forces to look for specific people to arrest if possible, kill if necessary.
No rounding up relatives, or razing villages.
The right way is never the easy way.
Luis, this is one matter, where all the options suck. The mensch needs to just decide which option sucks least, and be honest about it, and defend it with intelligence and consistency. What is the right option. given all that? Well, I don't know. Awareness of ignorance is the first step to knowledge.
