Lower the drinking age to 18

For years, it has been acceptable for legal adults of this country (18+) to go to war and die, yet it is illegal for them to have a beer. This is ridiculous and makes no sense. We, as citizens, are supposed to be granted all of our rights when we are adults, but this is not the case in America. This is the only country that still has the drinking age this high and it is pointless. To let someone die before they possess all of their rights as citizens is unjust and preposterous. The age during the last major time of war was lowered and since we are presently at war now, this should happen again and remain this way.
