As Hugh Fitzgerald once said, few in our time have the mental pencil to connect the dots on the most important (because deadliest) problem of this new century and millennium.
Let's make it easy:
Obama: Israelis have true peace partner in Abbas.
Abbas: We have the same policies as Hamas.
Hamas: Killing Jews is worship that draws us close to Allah.
And, for the dot-connection-challenged, a little more detail:
"Of course, Israel cannot be expected to negotiate with anyone who is dedicated to its destruction. But while I know you have had differences with the Palestinian Authority, I believe that you do have a true partner in President Abbas..." -- Barack Obama, March 21, 2013
"As far as I am concerned, there is no difference between our policies and those of Hamas." -- Mahmoud Abbas, March 15, 2013
"Israel will exist and will continue to exist until Islam will obliterate it, just as it obliterated others before it" -- Muslim Brotherhood founder Hassan al-Banna, as quoted in the Hamas Charter
"Killing Jews is worship that draws us close to Allah" -- Hamas's Al Aqsa TV
