Marine Gen. John Allen may be calling it quits after all. A source tells Politico that Allen is considering retirement, despite being cleared of wrongdoing in the Gen. David Petraeus scandal. Allen allegedly feels he’s “being pushed out for a variety of reasons,” namely the email debacle, which he fears will haunt him in his new post as NATO’s supreme allied commander in Brussels. “He doesn’t have a rabbi” at the Pentagon, the source said, especially with Defense Secretary Leon Panetta on his way out. A spokesman for Allen declined to comment on the report.
