Poland Is the Indispensable NATO Ally

Americans sometimes ask, with good reason, why Western Europeans don’t do more to defend themselves. Behold Poland, a NATO state setting an example for all of Europe as it goes on an arms-buying spree to deter Vladimir Putin or the next Russian czar.

Last week Poland announced a $2.3 billion deal to buy missiles and missile launchers from the U.K. for its air-defense systems. The company MBDA says the purchase is “the largest European short-range air defence acquisition programme in NATO” since the outbreak of the war in Ukraine.
