Explaining his proposal for setting up safe havens — he called them “enclaves” — Mr. Petraeus said they would be defended by Syrian rebels trained and supported by the United States. American and allied air power, and possibly a small number of American military advisers and support troops, would also help protect the areas.

Reminds me of the Yinon Plan:

The term Yinon Plan refers to an article published in February 1982 in the Hebrew journal Kivunim ("Directions") entitled 'A Strategy for Israel in the 1980s'. Kivunim was a quarterly periodical dedicated to the study of Judaism and Zionism which appeared between 1978 and 1987, and was published by the World Zionist Organization's department of Information in Jerusalem. The article was penned by Oded Yinon, a former senior official with the Israeli Foreign Ministry and journalist for the Jerusalem Post. It is cited as an early example of characterizing political projects in the Middle East in terms of a logic of sectarian divisions.
