Just ask President Obama -- or better, ask Jackson Diehl, Deputy Editorial Page Editor of The Washington Post. Back in 2010, Diehl described How Obama sabotaged Middle East peace talks:
So why does Abbas stubbornly persist in his self-defeating position? In an interview with Israeli television Sunday night, he offered a remarkably candid explanation: "When Obama came to power, he is the one who announced that settlement activity must be stopped," he said. "If America says it and Europe says it and the whole world says it, you want me not to say it?"
The statement confirmed something that many Mideast watchers have suspected for a long time: that the settlement impasse originated not with Netanyahu or Abbas, but with Obama -- who by insisting on an Israeli freeze has created a near-insuperable obstacle to the peace process he is trying to promote.
