Donald Trump talks terrorism at a campaign event Tuesday night in St. Clairsville, Ohio after the deadly terror attack on Istanbul's international airport. The presumptive Republican presidential nominee said we must "fight fire with first." Trump said the terrorists must think we're weak and stupid. Trump complained terrorists are allowed to get away with "chopping off heads, drowning people in steel cages," without the U.S. responding with waterboarding. "We can't do waterboarding -- which may not be the nicest thing, but it's peanuts compared to many alternatives. So we can't do waterboarding but they can do chopping off heads, drowning people in steel cages. They can do whatever they want to do. "They eat dinner like us," Trump said of terrorists overseas. "Can you imagine them sitting around the table or wherever they're eating their dinner, talking about the Americans don't do waterboarding and yet we chop off heads?" "They probably think we're weak, we're stupid, we don't know what we're doing, we have no leadership. You know, you have to fight fire with fire," Trump said to applause. "You have to fight fire with fire," Trump said at a campaign rally. "We have to be so strong. We have to fight so viciously. And violently because we're dealing with violent people viciously."
