Christian Ossentians are being goaded by al-Qaeda's Chechen branch to launch revenge attacks on Muslim Ingusentians who are by inlarge peaceful. So like Bin Laden sending Saudis to carry out 9/11 they sent in Ingush Muslim terrorists fighting for the Chechens in order to spread the war out if Chechnya. That is what the author means by "We could be on the eve of the next war."
We are at "War" with the zealots of the "religion of peace." The war has been raging (for a very long time.)
