You don't need to be military to swear an oath to love one's country and do what you can to help defend her.  Ask the French how important the French Resistance was during WWII.  Or look at the minutemen and those who fought in the Revolutionary War here.  We can swear to help defend our liberties and security it's our country if we won't help defend it however we can and be willing to voice and show our allegiance then we don't deserve this country! No war was won without the support of its people.  I find it insulting you think so little of our participation and that we take it so seriously.
