If Mr. Obama believes he can change the behavior of these nations by meeting without preconditions, he owes it to the voters to explain, in specific terms, what he can say that will lead these states to abandon their hostility. He also needs to explain why unconditional, unilateral meetings with Iran's Mahmoud Ahmadinejad or North Korea's Kim Jong Il will not deeply unsettle our allies.
If Mr. Obama fails to do so, voters may come to believe that he is asking them to accept that he has a "Secret Plan," and that he is hopelessly out of his depth on national security.
More interesting than the content itself is the idea that Mr. Rove wants to get conservatives talking about -- mocking -- Obama's "secret plan." Between Rove's speeches, say, at the NRA, and his WSJ op-eds, one gets the feeling like he's giving advice to the McCain campaign in the only way he can. (He does talk to some McCain advisers, but no forum better reaches McCain's donors and outside advisers than the op/ed page of the Journal.)
