What a sad day. Another sad day. My heart-felt condolences to the Russians and the world-at-large.
At the going rate of violence--and perhaps growing means with which these terrorists link up with each other I fear that no amount of carpet bombing, policing, profiling is going to make the world 'safe'. What can be done? Extreme measures can alienate a billion-plus people spanning 50+ countries in majority-population stage, along with sizable diaspora. That would be counter-productive. And no appeasement can be done either. So obviously thoroughly 'understanding' of issues are needed. International community needs to work together as part of some grand political measures to reduce, if not remove, the menace of global terrorism.
Ultimately all these acts of terrorism can be traced to political issues disguised in religion, ethnic, and nationalistic shrouds.
My understanding of the Chechen violence is that it is hardly Islamist--certainly not in the mold of the one which originates from the dreaded, dreary and suffocating places like Saudi Arabia and Yemen to invade other countries. The Chechens' is a nationalistic 'cause', dating back centuries. And yet, by these acts of terrorism, as someone rightly says above, 'the tipping point' reaches where no amount of victimhood can be discoursed when that victimhood resorts to such barbaric acts. Shame on those who support and make excuses for such barbarity. No matter how much blood the Russians may have spilled the proper route to 'fight' would be a guerrilla war INSIDE Chechnya by targeting soldiers IF violence is the only means left.
