Benito Mussolini, the Italian fascist, had declared, “War is to a nation what motherhood is to a woman.” He was wrong on motherhood. Pro-choice Italian women have reduced fertility rates from 2.4 percent in 1950 to just 1.31 today—amongst the lowest in Europe.
But he was more accurate on war tempering a nation. Consider Ukraine, which has courageously galvanised an ageing Europe towards self-reliance and strategic autonomy.
President Donald Trump, too, must get some credit for inducing long-term Western allies to bring more to the table.
The US, a major arms supplier and the world's greatest military power, necessarily has a binary view on war—profiting from soaring demand for military equipment, while helping allies via direct military intervention overseas, as it has done on several occasions since the Korean War in 1953.
