Retired Col. Cedric Leighton, a CNN military analyst, said Monday Sen. [crscore]Ted Cruz[/crscore]’s plan to carpet bomb ISIS “would be a violation of the laws of war.”

“CNN Newsroom” host Carol Costello asked Leighton, “Sen. Cruz says, you know, as sad as it is, civilian casualties are a fact of war, and civilians have died in wars that America took part in. So why would this be so different?” (RELATED: Army 3-Star: Mass Resignations If Trump ‘Bombs The S***’ Out Of ISIS [VIDEO])

Leighton explained, “Well, it’s different because the times have changed. Back in World War II when we went after targets like Nazi Germany or Imperial Japan, we did do carpet bombing.”

“What you saw at that particular point in time, because the targeting process was not as precise as it is now, you saw that kind of indiscriminate bombing occurring because that was the only bombing we knew how to do. Now we have precision-guided munitions. We have a precision targeting process. We go after high-value targets. So in essence, what Sen. Cruz is advocating would be a violation of the laws of war.”

Carpet bombing ISIS “could really not only hamper diplomatic efforts but political and military efforts that the United States would want to engage in after ISIS or even during the conflict with ISIS,” Leighton claimed.
