The British equivalent is to allow the British public to vote on an agenda instead of letting it go through Parliament. This is not the British way of deciding policy. Then let the Government try to implement Brexit even though it is going to cost the British economy a lot of money. Even then Government can't decide on how to implement the agenda and starts wasting money on truck convoys.
The Brits did the opposite, there was a perfectly working barrier called the Channel. The Brits decided to spend millions on tunneling under that barrier. A moat was always a good defense in the past.
