Your history and memory of his brother having created the "quagmire" in Vietnam which was followed by both Ted and Bobby leading the charge to abandon our friends there to a horrible fate does hit part of it. But, people should also remember that his father, Joe Kennedy, was also an admirer of Hitler and favored appeasement of Third Reich. If I'm not mistaken, Ol' Joe was recalled from his post as Ambassador to the Court of St. James at the insistence of Winston Churchill who, almost single-handedly, stood against the Nazi onslaught until help could arrive.
There needs to be a full unveiling of the lies and deceit and actual crimes carried out by and for the entire Kennedy clan going back well over 100 years. If Fat Ted will please continue to lead his name into infamy, perhaps it will facilitate the unmasking of the whole sordid family.
And then you have this~~"-In December 1952, Joe Kennedy called McCarthy and asked him to give his son Bobby a job on the committee. In January 1953, McCarthy named Bobby Kennedy assistant counsel. - Bobby appeared to be blind to McCarthy's demagoguery. "Joe McCarthy's methods may be a little rough," he told reporters, "but, after all, his goal is to expose Communists in government, and that's a worthy goal. So why are you reporters so critical of his methods?"
The Kennedy name should be included in the Webster definition of controversial.
