5 Reasons Arming Ukraine Won’t Work

With Secretary of State John Kerry [4] joining incoming Secretary of Defense Ashton Carter [5] as well as Republican Senators John McCain and Lindsey Graham [6] in publicly supporting U.S. efforts to supply lethal arms to Ukraine’s government to aid it in its war against separatist rebels and Russian troops in eastern Ukraine, it may look like a bipartisan consensus is emerging behind the idea.

Unfortunately, bipartisan approaches based on political convenience and wishful thinking—rather than clear foreign-policy logic—can be quite costly. George Kennan recognized the power of political pressure when he wrote that “a given statement or action will be rated as a triumph in Washington if it is applauded at home in those particular domestic circles at which it is aimed, even if it is quite ineffective or even self-defeating in its external effects.” The war in Iraq is a useful reminder of where this can lead if there is no serious discussion of the possible consequences of our decisions.
Recent proposals emphasize lethal defensive military assistance to Ukraine’s armed forces and suggest that providing it would demonstrate U.S. commitment to resisting Russian aggression and deter further offensive operations by imposing higher costs on Russia. While arming Ukraine may help Ukraine’s military kill more enemy soldiers, and might even increase the costs for Russia, it is quite unlikely that doing so will succeed in changing the Kremlin’s policy in Ukraine.
