Listening to President Obama and former Vice President Cheney give their respective national security speeches Thursday put me in mind of John Gray, author of "Men Are from Mars, Women Are from Venus."

Different men, different planets. Or are they?

Obama, standing before the U.S. Constitution and speaking to members of the Judge Advocate General's Corps, was the calm voice of confidence, redeemer of reason. He spoke loftily of American ideals and invoked our better angels.

Reiterating his case for closing Guantanamo, voted down by the Senate a day earlier, he also said there's no guarantee that terrorists won't attack again or that Americans won't die as a result. But, we'll win anyway. How?

His voice was also calm and reasonable, his remarks simultaneously sharp and blunt.

"The public was given less than half the truth," he said. "The released memos were carefully redacted to leave out references to what our government learned through the methods in question."

Hail, Mars! I'm thinking: This is just what the nation needs. Someone who shoots straight (well, figuratively speaking). Continued...
