It seems insurgents in Afghanistan and Pakistan are putting aside historical rivalries to cooperate in their efforts against the U.S. and coalition forces, coordinating joint attacks and combining for patrols. Formerly separate insurgent groups in Pakistan also are starting to behave like a syndicate. What’s more, they’re planning to stay and fight through the winter rather than retreat back to Pakistan, resulting in an expected 15 to 20 percent increase in attacks compared to last year. American military officials are looking on the bright side: If insurgents are cooperating, it’s a sign they’re feeling pressure from stepped-up coalition attacks. “They have been forced to cooperate due to the effect our collective efforts have had on them,” said a spokesman for coalition forces in Eastern Afghanistan.
