In a rare face-off on foreign policy, President Barack Obama and Republican rival Mitt Romney are swapping sharp criticism but exposing few clear policy differences on national security.
For Romney, who seeks to boost his foreign policy credentials with a high-stakes trip abroad, a lack of specific proposals has exposed him to criticism from Obama and his surrogates.
Obama's team has dug in on its efforts to cast the Republican as a national security lightweight while trying to capitalize on Obama's strength on such issues.
Romney's campaign has swatted away that criticism, but it's also shown few signs that Romney will offer more specific areas of contrast with Obama when he meets with world leaders beginning this week. Instead, Romney continues with broad jabs casting Obama as a timid leader.
