In the meantime, a stopgap can be employed. Ukraine already has foreign volunteers fighting in its ground forces. Why not ask for foreign volunteers or contractors to operate and maintain F-16s, A-10s, Gray Eagles and Patriots?

There is ample precedent for such a move. In 1941, Nationalist China bought U.S. P-40 fighter aircraft and set up the American Volunteer Group, better known as the Flying Tigers, to operate them. The Flying Tigers, composed of former U.S. military personnel led by Claire Chennault, helped save China from Japanese invasion.

Ukraine has millions of volunteers willing to risk death to defend their homeland. What it doesn’t have is enough weapons to arm its fighters. There is no excuse for this shameful failure. The nations imposing sanctions on Russia account for 65 percent of global GDP; Russia accounts for less than 3 percent. Russia cannot be allowed to outproduce Ukraine’s allies in armaments.
