I'm told there are clever young men in universities who say we shouldn't have. They write books about it. They get very good reviews — from each other.
Let me tell you what they're really saying. They're saying that in August 1914, when a great military power marched into a small neutral country whose independence we had guaranteed by solemn treaty — our signature, our word, since 1839 — we should have looked at the ledger, totted up the likely cost, and said: "Frightfully sorry, Belgium, but the figures simply don't work."
No. No, no, no.
Now, I am the last person to be sentimental about a piece of paper. "A scrap of paper" is precisely what the German Chancellor called it, and he was astonished we took it seriously. That astonishment is the entire point. A country whose guarantees are worth nothing has no friends, no influence and, eventually, no safety. The cheapest defence policy in the world is a reputation for keeping your word. The most expensive is having to rebuild one.
And let's not be naïve. It was not *only* the treaty. For four hundred years this country had followed one simple rule: no single power dominates the Continent and no hostile power sits on the Channel ports at Antwerp and Ostend. Philip II, Louis XIV, Bonaparte, the Kaiser — different flags, same problem. A Germany that had crushed France and cowed Russia would not have sent us a thank-you note for our neutrality. It would have sent us terms. And a Royal Navy facing a victorious continental empire with the shipyards of Europe behind it — well, one didn't need to be a chemist to see where *that* reaction was heading.
"But the cost!" they cry. Seven hundred thousand dead. The debt. The Empire. Yes. I know the cost. Every village in England has it carved in stone, and I have stood in front of enough of those memorials to feel the weight of it. But you cannot judge a decision by the price alone. You must ask what the alternative would have cost — and the alternative was not peace. The alternative was a Europe ordered by Berlin, with Britain isolated, friendless, and paying later with interest. We would have fought that war eventually, on worse ground, with fewer allies, and quite probably on our own.
