The John F. Kennedy legacy came up repeatedly during the Democratic National Convention. But today, would JFK even be a Democrat?

Kennedy supported, in today's lexicon, a George W. Bush-like "belligerent" approach to fighting the Cold War, and told CBS' Walter Cronkite it would be "a great mistake" to withdraw the American presence from Vietnam. In his 1961 inaugural speech, Kennedy said, "Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, in order to assure the survival and the success of liberty."

How would such a man feel about fighting today's global peril -- Islamofascism?

Barack Obama likes to point to the 1961 Kennedy-Khrushchev summit to support his desire for meetings "without preconditions" with enemies such as Iran and North Korea.

But Kennedy's secretary of State, Dean Rusk, urged against such a non-conditions-based summit. And later, Kennedy called the summit meeting the "roughest thing in my life. (Khrushchev) just beat the hell out of me. I've got a terrible problem if he thinks I'm inexperienced and have no guts." Indeed, Khrushchev thought Kennedy a weak amateur. Following the summit, Khrushchev built the Berlin Wall and placed missiles in Cuba, an action that led the world to the brink of nuclear conflict.

Kennedy believed in cutting taxes -- deeply and dramatically. Before Kennedy's tax cuts, the top marginal tax rate stood at over 90 percent, and Kennedy -- albeit after his assassination -- got it reduced to 70 percent, a much greater percentage reduction than did Bush. Kennedy, in a 1962 speech before the Economic Club of New York said, "It is a paradoxical truth that tax rates are too high today and tax revenues are too low and the soundest way to raise the revenues in the long run is to cut the rates now. The experience of a number of European countries and Japan have borne this out. This country's own experience with tax reduction in 1954 has borne this out. And the reason is that only full employment can balance the budget, and tax reduction can pave the way to that employment. The purpose of cutting taxes now is not to incur a budget deficit, but to achieve the more prosperous, expanding economy, which can bring a budget surplus."

In January 1963, Kennedy addressed Congress: "Lower rates of taxation will stimulate economic activity and so raise the levels of personal and corporate income as to yield within a few years an increased -- not a reduced -- flow of revenues to the federal government." Several days later, JFK sent another message to Congress: "Our tax system still siphons out of the private economy too large a share of personal and business purchasing power and reduces the incentive for risk, investment and effort -- thereby aborting our recoveries and stifling our national growth rate."
