There will always be extremists ready to commit acts of terrorism for whatever reason they may have .If the United states remains in this war on terror , then the war will never end. This war will end until every terrorist around the world has been defeated . Every single terrorist , that simply is not possible for the United states to accomplish . This war is not beneficial for the united states , mainly because it will never end .So we can also say that the costs of the war will be never ending , along with casualties.
