After I thought about a border hedge to replace a border wall or fence, I went looking for hedge pictures to make my case, and voila, see what I found.
Let's create a maze of hedges to slow 'em down. But how to maintain the maze without being attacked by someone trying to get to the other side? I'd have my landscaping trimmer sheers with me as a weapon. A patrol helicopter would have to follow me and my team of trimmers from above, maybe.
They can trim on their side. That's fine. As soon as they'd cut straight through, they'd be like that deer popping into the clearing. We could have rows of hedges; they'd quit trimming to get to the other side after a while: wall of hedge, followed by another wall of hedge, followed by another wall of hedge, and then a good old-fashioned row of "Kiss my border buns." If America is offensive enough, maybe nobody will want to cross the border, anyway, and maybe Mexico will plant their own hedge wall. The debate tactics of President Trump overflow into foreign policy. What are the good solutions to America's problems?
