When it comes to National Defense there is a huge difference between Liberals and Conservatives. Liberals believe that everyone should be equal. It just isn't fair that the United States has so much more fire power than other countries. They do everything they can to down size our military so that we aren't stronger than anyone else. This way they believe that no one will be mad at us and they will leave us alone.
Conservatives believe that the only way to have peace with bullies is to make sure you are convincingly stronger than the bully and that he knows you aren't afraid of a fight. For us in the US I believe this is not only a true principle but it is also the morally right thing to do. There are at least three other nations that are doing everything in their power to be the mightiest nation on earth. That would be China, Russia and Iran. History has shown that there will always be a super power, it is impossible for everyone to be equal. You tell me, who would you want to be the strongest nation on earth, the United States who has never taken land from another nation by force or Iran who has publicly declared that the Unites States is the great satan and who teaches that it is their duty to kill all infidels who will not convert to Islam?
Since 9/11/01 there have been 16,099 terrorist attacks that have resulted in the loss of human life. This number is certainly much higher since many terrorist attacks don't end up in international news. Terrorist attacks in military conflicts were not counted.
