The headline is just anti-American claptrap. The story is to cover any objectivity on the part of the US because Mitchell is not apparently solidly in the right wing Israel-from-Iraq-to-the-Nile camp. No US government has recognized the annexations of the Eastern part of Jerusalem or the Golan. Bush went so far as to acknowledge that Israel had created facts on the ground. And he did help drive Hamas into Iran's arms, just to distract and make peace more difficult. But even he didn't recognize any Israeli right of conquest. Your Foreign Ministry need not have made the report secret. The Obama Administration knows what contempt the Israeli government has for the current US government.
