You were not alone over there. You are not alone now. There are 20 million veterans who would give their lives for you. Please don't take yours. 

That from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth. -  President Abraham Lincoln
