Deterrence is one of the four basic strategies used to preserve security. Deterrence is a strategy whose sole aim is to discourage or avert any potential attack by terror groups or hostile nations. The US government uses several strategies in its national security mandate and none of them can be totally effective if implemented alone. This means that any strategy must be enforced in tandem with others and the coordination of those strategies being dependent on several agencies of government. Terror groups exploit any weakness in law enforcement and disaster preparedness to launch terror attacks on the American soil and its allies across the world. They also depend on financing from sympathizers and state governments who condone terrorism against states they perceive to be enemies. America therefore uses reorganization of its security organs, its defense policies and mostly foreign policies including sanctions as deterrent strategies against terrorism and foreign aggression.
The US government has categorically said that it will continue with its no negotiating with terrorists’ approach and its zero tolerance to nations that harbor or aid terror activities. This means that it makes it quite clear that it will use all facilities, among them military power, to deter any potential acts of terror if doing so means a preemptive attack on associated nations. This discourages nations from harboring or sponsoring terrorists since as in is the case of the Taliban in Afghanistan, the consequences can be dire. The government also uses sanctions and other diplomatic efforts as a tool of discouraging sympathizers of terror groups. The government has demon stared its seriousness to deter terrorists from penetrating the American nation by conducting the largest enforcement agencies reorganization and restricting since the Truman regime. One of the new departments that came to be from this effort is the department of homeland security which further strengthens the war against terror.
