Platitudes are a wonderful thing. Like Chinese fortune cookies they contain irrefutable truisms. They are politically safe, media-solid, voter-tested and reassuring, gaffe-averse and on many occasions happen to have validity and viability.
One thing platitudes (or cliches, or slogans) do not constitute is coherent policy. On the other hand, and despite Bruce Riedel's wise column here in Al-Monitor asking for policy prescriptions, perhaps "Presidential Debates" are not a forum in which you should or are expected to make serious policy proposals. Certainly not on the Middle East. President Barack Obama at least made an effort to explain his policies and asked voters to trust multilateralism and diplomacy. Mitt Romney just conveniently found refuge in the warm confines of platitude-land.
