Can you imagine what would have happened if some wide spot in the road had kidnapped a boat full of 'Er Majesty's tars back in the days of Pax Britannia?
HMS Thunderer would have dropped anchor in the harbor of whatever pathetic hamlet they were being held captive. Royal Marines would have been disembarked. Crowds of Wogs would have been mowed down by Gatlings and run through with Martini bayonets. The local rajah would have forked over his prisoners, or he would have found his house burned to the ground and Tommy Atkins pissing on the ashes.
This is what used to be called a casus belli.
Now it's just called a human interest story.
How are the mighty fallen!
