The general in charge of the campaign against the Islamic State in Iraq and Syria (ISIS) is rejecting Sen. Ted CruzTed CruzDemocrats pounce on Cruz's Supreme Court comments Brent Budowsky: An epic battle for the future of Congress Cruz: Precedent exists for keeping Supreme Court short-staffed MORE's call to carpet bomb the terrorists group.

"We are bound by the laws of armed conflict," Army Lt. Gen. Sean MacFarland said Monday, when asked about that strategy.

"Indiscriminate bombing, where we don't care if we're killing innocents or combatants, is just inconsistent with our values," he continued.

"And it's what the Russians have been accused of doing in parts of northwest Syria. Right now we have the moral high ground, and I think that's where we need to stay."

Cruz, a 2016 contender, suggested in a speech Dec. 5 that he would carpet bomb the terror group if elected president.

"We will carpet bomb them into oblivion. I don't know if sand can glow in the dark, but we're going to find out," he said  

During a Dec. 15 GOP debate, Cruz said he wanted to focus air power on ISIS.

"You would carpet bomb where ISIS is -- not a city, but the location of the troops. You use air power directed -- and you have embedded special forces to direction the air power. But the object isn't to level a city. The object is to kill the ISIS terrorists," he said. 

During last week's Fox Business Network debate, Cruz doubled down on his vow to carpet bomb ISIS. 

Cruz said he would "apologize to nobody for the vigorousness with which" he would fight ISIS. 

But MacFarland cautioned Monday that how the U.S. defeats ISIS is important.

"At the end of the day, it doesn't only matter whether or not you win, it matters how you win," he said. 

"And we're the United States of America and we have a set of guiding principles and those effect the way we as professional soldiers, airmen, sailors, Marines, conduct ourselves on the battlefield."
