I tend to agree with General Flashman in George Macdonald Fraser's book Mr American:
"Mr Franklin asked the General what he thought of the war situation. The old man shrugged.
"Contemptible - but then it always is. We should stay out and to hell with Belgium. After all it's stretching things to say we're committed to them and we'd be doing them a favour - and the Frogs too."
"By not protecting them you mean? I don't quite see that"
"You wouldn't - because like most idiots you think of war as being between states - coloured blobs on the map. You think if we can keep Belgium green, or whatever colour it is, instead of Prussian blue, then hurrah for everyone. But war ain't between coloured blobs it's between people... Imagine yourself a Belgian - in Liege say. Along come the Prussians and invade you. What about it? - a few cars commandeered, a shop or two looted, half a dozen girls knocked up, a provost marshal installed and the storm's passed. Fierce fighting with the Frogs, who squeal like hell because Britain refuses to help, the Germans reach Paris, peace concluded and that's that. And there you are, getting on with your garden in Liege. But" - the General waved a bony finger. " Suppose Britain helps - sends forces to aid little Belgium - and the Frogs - against the Teuton horde? What then? Belgian resistance is stiffened, the Frogs manage to stop the invaders, a hell of a war is waged all over Belgium and north east France, and after God knows how much slaughter and destruction the Germans are beat - or not as the case may be. How's Liege doing? I'll tell you - it's a bloody shambles. You're lying mangled in your cabbage patch, your wife's had her legs blown off, your daughters have been raped, and your house is a mass of rubble. You're a lot better off for British intervention aren't you?" He sat back grinning sardonically.
"By that reckoning," said Mr Franklin, "no one would ever stand up to a brute or a bully"
"Course they would - when it was worth while. You don't remember the war of 1870 - when those same Germans marched on Paris. Smallish war- but suppose we'd been helping the Frogs then? It wouldn't have been over half so quick, and God knows how many folk would have died who are still happily going about their business in Alsace and Lorraine. Same thing today - we should simply tell the Kaiser that if his fleet puts its nose out of the Baltic we'll send it to the bottom - that satisfies the Frogs up to a point, since it guarantees ther northern coast, it satisfies the Kaiser who'll swallow his pride for the sake of keeping us out of the war, and it save his pretty little ships as well. And five years from now, Liege will be doing rather well - whether it's got a German provost marshal still or not. And that won't matter a damn, to people whose main concern is eating, drinking, fornicating, making money and seeing their children grow up safe and healthy"
