This year marks the 50th anniversary of the assassination of President John F. Kennedy, a tragedy for our nation. Today, we remember and honor his hard work. We continue to be inspired by his positive attitude, by his sense that if Americans put their minds and backs into something, that it could be done, no matter the degree of difficulty. His optimism was contagious; he believed that America’s best days were ahead, and that the United States should be a leader among the nations of the world. He set lofty national goals - from space exploration to conquering hunger and racial inequality here at home. JFK challenged Americans to be great. And as Americans, we still strive to meet his highest expectations. This is perhaps his greatest legacy.
