I really hate reportage like this. Every government, even seemingly incompetent ones like the current crop in the UK, have hundreds or thousands of contingency plans for things of wildly varying likelihood. This is just one of those things.

This is just as informative as those articles that say eating sugar triggers the same receptors as cocaine. Yes it's true, but there aren't that many reward mechanisms in the brain, so a lot of shit hits those same receptors.

It's data and it's true, but it's not useful information.
