The article mentions J Street lobbying for Israeli unilateral concessions. It is explicitly stated in J Street's policies that they prefer diplomacy over military action if possible, and multilateral vs. unilateral decisions. There are other falsehoods in this report and others relating to J Street, but don't take my word. You can visit http://www.jstreet.org/page/policy .
