Former US general says Israel's success in Gaza 'very limited'

The former commander of US Central Command, General Frank McKenzie, described Israel's success in its objectives in Gaza to date as "very limited".

"They set themselves a goal of removing the political echelon and the military leadership echelon of Hamas when they went in. They have not been successful to date at doing either," he told CBS's Face the Nation.

McKenzie also noted the larger issue in his opinion is that "you have to have a theory for what it's going to look like when it's over" - stressing that "you need a vision of an end state when you begin a military campaign because everything you do then subtracts or adds to your ability to get to that point."

Israeli occupation is "the least desirable of all outcomes," he added, going on to say that Arab states in the Middle East will need to assist efforts in post-war Gaza.
