Everybody fears the next big war in all of the wrong places!

The thermonuclear apocalypse of World War III will be ignited when België invades Eire in a dispute over beer.

The Germans will try to sit this one out, whilst laughing at them both.  But nobody will survive the rising tide of war, after it is revealed that the Irish have been using the Guinness brewery as cover for a secret atomic weapons programme.  (Protip:  Guinness is radioactive—Irishmen are proud of this.)

After the Irish turn Belgium into a parking lot, the Germans just will not be able to resist driving on through to circumvent the mushroom-farm bunkers of the Maginot Line, and settle some old scores with the French.  Roused to Gallic fury in the spirit of Roland, the French will then decide to invade Russia for a rematch of that embarrassing little tiff in 1812.  The Russians will then decide to nuke America just on principle; and as his final act in office, the very last American President (whoever that may be) will elect to trade some nukes with the Chinese.

Then, everybody will nuke Poland.  Just because.

After the insapient talking monkeys are done nuking each other to total extinction, and the whole world has been made blessed terra nullius, the robots will emerge from their secret underground bunkers, and rule a joyously humanfree world with everlasting peace.

It all starts with beer.  See?

Beer is the cause of world peace. 🙃☮
