Want speculation? Let's do it. For the end of Babylon the Great, something like this. The Ayatollahs in Iran and it's crazy pursuit of a nuclear bomb get cut short. The US, Saudi Arabia, Israel and Iran become at war and as a result Iran religious capital Quom get obliterated. Iran retaliate destroying Mecca and attacking Jerusalem. Other demented terrorists out of craziness destroy the Vatican.
That gets you 'Babylon the Great destroyed in one hour'.
Of course this kind of wishfully thinking is not going to happen. There's too much security around the world.
The thing that worries me is how the Borg is gonna react if there's some kind of 'incident', are they gonna start a message of doom? Are they going to circle the wagons? That's what the article says too.
