Once military service commences, what happens next is largely a matter of chance. Rarely does one choose to be a hero. The service-person is expected to perform honorably whether he/she is a Special Forces operative or is issuing underware to recruits. Upon discharge the soldier or sailor, if he/she has served honorably, carries the memory of their sevice with pride.
It is a dis-service to veterans to use military service as a campaign issue, especially in a high visibility election. The Commander-in-Chief has no business besmearching the military service of ANYONE, including their opponent. The Bush and Kerry camps both owe an apology to those who value and respect the service they performed.
