Despite his immense popularity around the world, Mr. Obama will confront resentment over American-style capitalism and resistance to his economic prescriptions when he lands in London on Tuesday for the Group of 20 summit meeting of industrial and emerging market nations plus the European Union.
What Obama appears to not realize - or perhaps he doesn't care - that the US's strident assurances about how Western finance, based on the concept of fractional banking, will save the world's economy, has brought world economy to a standstill.
He appears not to realize - or to care - that every time a US- piloted drone somewhere kills women, kids, and the elderly, this country is creating another generation of young radicals are righteously and rightfully angry. That anger will have only one way to express itself, and that doesn't at all augur well for the future of peace on this planet.
He appears not to realize - or to care - that US military misadventures around the world to steal resources - rather than acquire them through treaties, as Russia has done - make us look as though we have a "psychotic thug" class of juveniles running this country.
He appears not to realize - or care - that the billions of dollars sent to Israel - a country doing its level best to ethnically cleanse every Palestinian from any part of its territory, does not make us look like an honest broker to the rest of the Middle East, or the world.
And unfortunately for this President, those intellectual capabilities with which he is remarkably endowed, mean nothing if the only guiding emotion in his life is hubris.
Hubris, like ignorance, should be painful.
