The American military and intelligence has done an exceptional job in protecting our country's security. National security in an era where terrorist attacks are the greatest threat must focus on intelligence and military trained Special Forces operations rather than continuing to send American soldiers and military personnel to fight conventional wars. America faces unconventional enemies that will not be defeated by conventional military tactics.
National security also means striving for a future of energy and economic independence. In its simplest terms, our current system borrows from Peter to pay Paul. We cannot guarantee our own national security while relying on the rest of the world for our basic energy needs.
