The former head of the Defense Intelligence Agency on Sunday described President Obama's Middle East policy as one of "willful ignorance," saying the administration needs a clearer strategy for dealing with conflicts emerging across the region.

Lt. Gen. Michael Flynn said during an interview on "Fox News Sunday" that recent developments in the Middle East are moving in a bad direction for the United States, with Iran "clearly on the march" to influence events in a "regional sectarian war."

Critics of the administration have pointed out that the United States appears to be siding with Iranian-backed rebels against the Islamic State in Iraq and Syria but opposing such fighters in Yemen.

“At the end of the day, we have just this incredible policy confusion — never mind what our strategy is to execute that policy," Flynn said. "We have to stop what we’re doing and take a hard look at everything going on the Middle East because it’s not going in the right direction."
