Eisenhower's worst fears came true. We invent enemies to buy the bombs

Why do we still go to war? We seem unable to stop. We find any excuse for this post-imperial fidget and yet we keep getting trapped. Germans do not do it, or Spanish or Swedes. Britain's borders and British people have not been under serious threat for a generation. Yet time and again our leaders crave battle. Why?

Last week we got a glimpse of an answer and it was not nice. The outgoing US defence secretary, Robert Gates, berated Europe's "failure of political will" in not maintaining defence spending. He said Nato had declined into a "two-tier alliance" between those willing to wage war and those "who specialise in 'soft' humanitarian, development, peacekeeping and talking tasks". Peace, he implied, is for wimps. Real men buy bombs, and drop them.

This call was echoed by Nato's chief, Anders Fogh Rasmussen, who pointed out how unfair it was that US defence investment represented 75% of the Nato defence expenditure, where once it was only half. Having been forced to extend his war on Libya by another three months, Rasmussen wanted to see Europe's governments come up with more money, and no nonsense about recession. Defence to him is measured not in security but in spending.

Libya has cost Britain £100m so far, and rising. But Iraq and the Afghan war are costing America $3bn a week, and there is scarcely an industry, or a state, in the country that does not see some of this money. These wars show no signs of being ended, let alone won. But to the defence lobby what matters is the money. It sustains combat by constantly promising success and inducing politicians and journalists to see "more enemy dead", "a glimmer of hope" and "a corner about to be turned".

Victory will come, but only if politicians spend more money on "a surge". Soldiers are like firefighters, demanding extra to fight fires. They will fight all right, but if you want victory that is overtime.

Eisenhower

It is not democracy that keeps western nations at war, but armies and the interests now massed behind them. The greatest speech about modern defence was made in 1961 by the US president Eisenhower. He was no leftwinger, but a former general and conservative Republican. Looking back over his time in office, his farewell message to America was a simple warning against the "disastrous rise of misplaced power" of a military-industrial complex with "unwarranted influence on government". A burgeoning defence establishment, backed by large corporate interests, would one day employ so many people as to corrupt the political system. (His original draft even referred to a "military-industrial-congressional complex".) This lobby, said Eisenhower, could become so huge as to "endanger our liberties and democratic processes".

I wonder what Eisenhower would make of today's US, with a military grown from 3.5 million people to 5 million. The western nations face less of a threat to their integrity and security than ever in history, yet their defence industries cry for ever more money and ever more things to do. The cold war strategist, George Kennan, wrote prophetically: "Were the Soviet Union to sink tomorrow under the waters of the ocean, the American military-industrial complex would have to remain, substantially unchanged, until some other adversary could be invented."
