This blog will examine more closely NATO’s history of national caveat imposition in NATO military operations. It will begin by providing 5 reasons for caveat imposition within NATO missions. It will subsequently outline the recurring habit of NATO nations to contribute caveat-constrained military forces to NATO missions around the world over two decades, in Bosnia, Kosovo, Somalia, Libya and most notoriously in Afghanistan. It will next describe the crux of NATO’s “caveat problem”, and then describe the three, largest, negative, caveat effects that have continuously resulted from NATO caveat imposition, namely (1) divided and inflexible NATO forces; (2) a disunified Multinational Force incapable of performing fundamental tasks; and (3) inequality and uneven burden-sharing within each NATO Multinational Force. Lastly, I will offer some final thoughts on this important issue of national caveats within NATO missions, with reference to the purpose and future of the NATO Alliance in global security affairs.
