The proposed fence across the southern U.S. border with Mexico is, at best, an expensive and stupid idea. Faced with a fence illegal border crossers can simply climb over it, make a hole in it or dig under it. A fence is not the best deterrent to those determined to trespass. A much better way to defend and protect property is a moat. A Middle Age defense, a deep wide moat always worked better than a fence.

To put in a border moat just dig a wide deep trench across the U.S. southern border (California, Arizona, Texas), about 50 feet deep and about 1 mile wide. The moat could be built by the Army Corps of Engineers, using bulldozers, steam shovels, etc. Then, after the moat is built, fill it with water from the Gulf of Mexico. There’s your moat. Then, take all the leftover mines from World War II and Vietnam and mine the moat. Then add alligators. Lots of alligators.

Forget the fence, vote for a moat! It’s quicker, easier and cheaper. Plus, a moat would be low maintenance; no border patrol, no surveillance, no Minutemen and you don’t even have to feed the alligators.

And, politically, to appease extreme left wing liberals, environmentalists and our friends and neighbors south of the border (who benefit greatly from their poor and unemployed leaving there and coming here - and sending tens of billions of American dollars back there) we could call the moat a “irrigation, recycling and wildlife project”.

You want a secure border? You want to stop people from illegally entering the U.S. from Mexico? Forget the fence, vote for a moat!
