(CNSNews.com) - In a joint press conference with Colombian President Juan Manuel Santos, President Donald Trump issued a short direct answer to whether his proposal to build a wall along the U.S.-Mexico border will be a positive step towards stopping the flow of drugs across the border - "Walls work. Just ask Israel."
Trump's response followed that of Santos, who said, "I believe that the best way to fight the drug trafficking is by collaborating."
"This is not a problem of Colombia only or a problem of the United States only. It's a world problem, and we have to all work together. We declared the war on drugs 40 years ago. The world declared war on drugs, and it's a war that had not been won, so we must be more effective and more efficient," Santos said.
Santos said the U.S. and Colombia must work together to fight drug trafficking. He said his country has already made great strides in this effort - destroying 22,000 laboratories in the Colombian jungles and seizing cocaine in transit.
"We have destroyed 22,000 laboratories in the Colombian jungles, seizing the cocaine in the transit. We have seized record amounts of tons last year, and this year, we're doing even better than last year. So by working together, we can be much more effective, and that is a commitment we just made or ratified this afternoon," Santos said.
"That was a long and very diplomatic answer to your question," Trump said. "I will say a little bit shorter: Walls work. Just ask Israel. They work. Believe me, they work, and we have no choice."
