In recent months Obama has shown ( at least in rhetoric ) signs of willingness to start " real " peace process, however the signs have been always overshadowed by the unwillingness of the Zionist regime to stop the illegal settlements, in fact the regime humiliated U.S vice president Joe Biden by announcing the construction of 1600 illegal houses in East Jerusalem during Biden`s recent visit. President Obama is said to be " furious " about the announcement of the constructions to which prime minister Netanyahu said he didn`t know about and offered his apologies to Washington ! Now few weeks later in his AIPAC speech , Netanyahu said " Jerusalem is not a settlement. It is our capital ". In other words , Israel considers the illegal settlements as " legal ".
Interestingly at the same AIPAC stage , sec. of state Hillary Clinton said that the status quo between Israelis and Palestinians was “unsustainable” and that building over East Jerusalem hurt efforts to advance the peace process.
Personal answer to the posting. Obama is serious enough for hard talk , but not serious enough for concrete actions to force the Zionist regime stop its violations of international law ! In fact Obama seems now to be more focused on Iran`s nuclear program than on Palestinian issue !
