Obama is useless, as in soup-to-nuts useless and then some. The "and then some" means wrecking America's alliances and emboldening America's enemies. Has he no friendships with foreign leaders? Britain? Fuhgeddaboudit, that romance is swimming with the fishes. France? Sarkozy looks down his distinguished nose at Obama's "virtual" foreign policy to Iran and says so at the UN. "Zut alors! 'oo eez ze surrender monkey?" (while refusing troops for Afghanistan). Where are the African leaders fêting Obama? Indonesia? Nope. India? China? Nope, nope. Venezuela? Iran? N. Korea? Brazil? Russia? Nope, nope, nope, nope, nope.
Obama’s problem is that most other world leaders are not empty suits but people of some accomplishments. As these leaders have met and assessed him as of no consequence, in effect agreeing with Bill Clinton that Obama is little more than a coffee boy elected via celebrity syndrome, they have little interest in him and he realizes that he is not of their caliber either. Consequently, once past the pleasantries and the weather, neither has much to say to the other.
