By Sen. Mike Lee A treaty commitment to Ukraine is a dangerous liability with no upside. NATO Secretary General Jens Stoltenberg proclaimed that “Ukraine will join NATO…. It is not a question of if, but when.” Fortunately for the United States, the admission of Ukraine into NATO cannot be forced upon us by the unilateral dicta of global elites. Nevertheless, Stoltenberg’s shocking display of hubris and blatant disregard for sovereignty reminds us exactly why a nation should not be added to the NATO alliance without weighing the risks.
