For example, hypothetically, what is the chance for a major NATO country will never have a president that might decide to bomb another country out of the blue, because that country according to said president, has weapons of mass destruction, despite the fact the same country intelligence said the target DOESN'T have such weapons? This will never happen right?
Even in Russia, only complete loonies treats this as a plausible scenario. That's why you can see bunkers and anti-tank ditches and defensive lines being built on the European side of the Russian border, and nothing of this sort on the Russian side. They don't even have a basic chain-link fence. Mushroomers sometimes get lost and just walk into Russia.
You do realise that the parent was actually making a historical reference? "Weapons of mass destruction"... doesn't that ring a bell?
