It’s instructive to look at which ally spends the greatest proportion of its GDP on defense. At the top of the list isn’t Britain, which has fought alongside the United States in Iraq, Afghanistan, Libya, and in operations against the Islamic State. Nor is it the Germans, who, with their paltry 1.2 percent, have made the third-highest troop contribution to the counter-Islamic State campaign. The winner is Greece, which allocates 2.4 percent of GDP to defense but can hardly be considered NATO’s vanguard. (It has helped the numbers that, while Athens slashed its defense spending in absolute terms, its GDP has shrunk faster still.) Today, Portugal is closer to the target, percentage-wise, than the Dutch, and Albania is closer to it than Canada. Clearly such budget numbers tell just part of the story at best.
A more accurate evaluation would look to other important criteria. Some allies bring niche capabilities to the fight, such as Dutch, French, and Spanish special operations forces and British maritime assets, while others, like Italy and Turkey, are integrated into America’s extended nuclear deterrent. Still others host American bases or troops on rotation. At times, allies shoulder some of the defense load in certain arenas. France, for example, took charge of counterterrorism operations in Mali, allowing the United States to focus on other areas. When Germany declined to participate in the 2011 NATO operation in Libya, it subsequently picked up other missions, like patrolling the Aegean Sea in 2016 and deploying a battle group to Lithuania this year.
A broader measure would also look at allies’ reliability and their will to stay engaged in grinding fights. According to the latest available statistics, Denmark and Britain have suffered more fatalities per capita in Afghanistan than has the United States, with Estonia and Canada not far behind. Such comparisons can be crude, but they demonstrate one dimension of their willingness to remain in a war engaged by NATO to defend America, rather than the other way around.Read it all here. One reason that the budget numbers are so misleading is that some countries (such as Greece) use their military as a jobs program without any significant military capability. Others, such as the UK, Germany, and Denmark have highly efficient and effective militaries. All should do more, but we should not focus too much on the budget numbers.
