I think a big difference is the accomplishments you listed are one thing. Leadership. JFK had a passion for the moon landing, etc. I think if you look back at our greatest accomplishments, it's because whoever was leading the nation at the times led w/passion and we responded in kind. I believe that's what's missing here. Of course we can build a wall along the entire border - if our leadership really wanted to.
Thanks. You're making a great point, too. And it goes to show you how far we've fallen. As much as I'm no fan of the Kennedy's, including JFK, he DID show leadership on the space race and other things. It's a sad day when the head of the Republican party in the White House looks so weak compared to any Kennedy.
Our leadership is dedicated with bringing the illegals out of the shadows. Only the House can save us from this "leadership".
