It’s useful to recall what we generally expect allies and strategic partners to do for us. In Europe, Asia, and elsewhere in the Middle East, they provide bases and support the projection of American power beyond their borders. They join us on the battlefield in places like Kuwait and Afghanistan or underwrite the costs of our military operations. They help recruit others to our coalitions. They coordinate their foreign aid with ours. Many defray the costs of our use of their facilities with “host nation support” that reduces the costs of our military operations from and through their territory. They store weapons for our troops’, rather than their own troops’ use. They pay cash for the weapons we transfer to them.
