Two points: (1) We already had a timeline. Obama set a one year timeline exactly a year ago. Now he wants another year? (2) No proposal from the Quartet is serious if it backtracks on the previous Quartet position on Settlement construction and Obama's negotiation parameters. A SERIOUS Quartet proposal would require that Israel must stop all Settlement construction in occupied territory until a negotiated peace agreement is completed, and would be backed up with a Security Council resolution. Now I know why George Mitchell resigned. He discovered that President Obama was not serious, in spite of his promises.
