The bombers could have been from Chechnya or Mali or Bosnia or Iraq or Egypt or Afghanistan or any Muslim country where Islamists are active.
Now that we know who the bombers are and one of them is dead, and that they are Chechen Muslims, the media has gone into "Palestinian" mode insisting that we need to talk about the conflict in Chechnya.
We can talk about Chechnya, but the issue there and everywhere else is Islamic nationalism or Islamism. The bombers could have been from Chechnya or Mali or Bosnia or Iraq or Egypt or Afghanistan or any Muslim country where Islamists are active. And that's most Muslim countries, especially after the Arab Spring.
There is a conflict in Chechnya and Iraq and Pakistan and Afghanistan and Thailand and Nigeria and the Philippines and India and Israel and France and a hundred other countries.
Where there is a sizable Muslim majority or even sizable minority, there is conflict.
Any talk about pressuring Russia into "resolving" or "appeasing" Chechen Islamists (at least the ones not allied with Russia) is a silly waste of time.
Russia isn't Israel. It's not going to be intimidated into making deals with terrorists. And talking about the demands of Chechen Islamists is a waste of time. Their demands are the same as the demands of all Islamists.
Islamism is Transnational. You cannot solve it locally. The situation in Israel has proven that. Giving in to territorial demands always fails because a transnational movement wants more than a few miles here and there. They want a regional and then a global Caliphate.
America had nothing to do with the conflict in Chechnya. That didn't stop Dzhokar Tsarneav and Tamerlan Tsarneav from carrying out the mass murder of Americans.
To understand Dzhokar Tsarneav and Tamerlan Tsarneav is to understand that Islam is transnational.
"World view" is listed as "Islam" and his "Personal priority" is "career and money".
He has posted links to videos of fighters in the Syrian civil war and to Islamic web pages with titles like "Salamworld, my religion is Islam" and "There is no God but Allah, let that ring out in our hearts".
It's Allah Akbar all over again.
