Step #1 should be to dig up that murderer Ted Kennedy and thrown his bones into the Potomac. Then fumigate the plot and it will be fit for someone who deserves to be there.
Teddy Kennedy did serve in the US Army during the Korean War, but not in Korea; thus he may have qualified under the existing rules at the time of his death in 2009. I’m no fan of Teddy and agree that he worked to betray the USA during President Reagan’s administration.
From Wikipedia:
In June 1951, Kennedy enlisted in the United States Army and signed up for an optional four-year term that was shortened to the minimum of two years after his father intervened.[13] Following basic training at Fort Dix in New Jersey, he requested assignment to Fort Holabird in Maryland for Army Intelligence training, but was dropped without explanation after a few weeks.[13] He went to Camp Gordon in Georgia for training in the Military Police Corps.[13] In June 1952, Kennedy was assigned to the honor guard at SHAPE headquarters in Paris, France.[2][13] His father’s political connections ensured that he was not deployed to the ongoing Korean War.[2][17] While stationed in Europe, he traveled extensively on weekends and climbed the Matterhorn in the Pennine Alps.[18] After 21 months, he was discharged in March 1953 as a private first class.[13][18]
