Imagine if it was still as it was in 1971 and our nation was invaded by some advanced rogue state. Might the message of hostility be along the following lines:
'Your collectivist inefficient industrialized infrastructure is as nothing compared to our superior technological might. By the power invested in us from utterly reasonable and progressive views of sexual equality, we laugh at your pathetic attempts to thwart our invasion by means of self destructive general strikes and three day weeks.
We do not fear your wasteful and horrific workplaces that send men underground to ultimately die of respiratory industrial diseases in the name of close knit community. Nor do we fear your irrational isolationism from the rest of the world based on a misplaced view of the greatness of your nation.
Your outdated views of racial division, akin to slavery in our minds, will not prevent the invasion of your great nation. We have all seen your situation comedies and your Bernard mannings and we know the truth.
You may have government run transport networks, a society where everyone knows their place, and a class system riddled with class and a lack of social mobility, but we have superior weapons, finances and efficiency.
Your outdated, post industrialist naive views that no one does a hard days work without mining a coalface with their own teeth is as nothing compared to our computer guided missile technology.
Your criminal laws of evidence that actively discriminate against Jews does not scare us, nor does your death penalty or complete absence of a recognition of human rights (especially following the horrors of WW2).
You might find refuge in Bejam, but we have lidl. And we fear not this nylon of which you speak.'
I have to say, if this was the message, I'm sure we'd all rally round together and defeat this hideous aggressor.
