The conflict in and around Afghanistan is entering a decisive phase. The International Security Assistance Force (ISAF), armed with a new counterinsurgency (COIN) doctrine and resources to conduct a forceful campaign, is engaging in a counteroffensive against the insurgency. Drawing on lessons learned from their own past insurgencies both regionally and globally, the insurgents are also constantly changing tactics. The inevitable clashes between the use of force and use of violence will exact a heavy cost in human lives this year.
