On the basis of what research does N. P. E. Wheeler assert that “if you want peace, prepare for war” is still true (Letters, 18 November)? The easing of tension between the US and Russia was accompanied by a decrease in arms, which contradicts the saying. And, if it were true, it would predict that countries with the fewest weapons are the most war-prone, which does not appear to be the case.
