Just Say No: America Should Avoid These Wars

The bipartisan U.S. foreign-policy establishment seems to only know how to generate new wars. None end well.

Critics of U.S. foreign policy often complain that a president has no strategy. What they usually mean is that the president's strategy does not assign a sufficiently high priority to their favorite overseas projects. It is a useful exercise to review how many projects critics of this president now have in mind, projects that require significant U.S. military power, and which risk the need for even greater force if they go awry. To attempt all of these projects simultaneously would violate a basic principle of strategy—the principle of concentration.

Between Europe and the greater Middle East, important members of the foreign-policy establishment, Republicans and Democrats, now support five major military projects—in Ukraine, Iran, Syria, Iraq and Afghanistan. (Waiting just offstage is the containment of China.) Some, such as Senator John McCain (R-AZ), support all five. Others only speak enthusiastically about one or two projects, but do not recommend restraint on others. Were the U.S. president to accept the advice of these worthies, he would be making foreign policy not the "shield of the republic," but its purpose. All domestic problems would take a back seat. Let us review the costs, risks and odds of success of these policies.

Perhaps the riskiest policy has been proposed by a group of muscular liberal Atlanticists— all veterans of senior foreign- and defense-policy positions— who demand that the United States supply a billion dollars a year worth of military equipment to Ukraine to thwart Russian aggression. In his confirmation hearings, Defense Secretary designate Ashton Carter seconded the motion.

The purpose of this effort is to increase the cost to Russia of supporting secessionists in the breakaway provinces of Luhansk and Donetsk, thus producing some unspecified happy outcome. These advocates offer no clear statement of U.S. strategic interests in the conflict, because there aren't any. Russia is at best a middle power in decline, weaker economically than any of the middle powers in Europe, and these provinces can affect that trajectory almost not at all. The outcome of this fight can have no effect on American security. But, it is clear that Russia perceives itself to have important strategic interests there. Russia is much stronger than Ukraine. The question needs to be asked, is it likely that these U.S. weapons could make much difference in the outcome if Russia is as committed as it seems? The answer is probably not. The next question is, what do these experts recommend the United States do if Russia is undeterred by a modestly improved Ukrainian army? Are they willing to accept an obvious defeat for U.S. arms and assistance? Or is their plan to escalate? Given the strategic unimportance of the stake, is escalation of this conflict with a nuclear-armed Russia in the U.S. national interest?

Project number two is the effort to end the Iranian nuclear-energy program. The president, leading a group that includes Russia, China, Britain, France and Germany, is trying to negotiate an agreement with Iran that will bring this energy program under intense surveillance, and reduce the size of the program such that it would take some time for Iran to move from a decision to an actual nuclear weapon. Economic sanctions and the collapse of oil prices have presumably played an important role in bringing Iran to the negotiating table. But for some in Congress, the expert community, and for Israeli Prime Minister Benjamin Netanyahu, this is not enough. They want Iran to have no capability. And they seem willing to deprive the president of the carrots he needs to induce Iran to cooperate. So what if the opponents of diplomacy succeed? These critics do have a happy ending in mind; ever-stricter sanctions that will somehow cause Iran to capitulate. This seems unlikely, because other states will likely abandon the sanctions regime if Congress proves an obstacle to an agreement. And when this happens, only one option will remain—a U.S. military operation to destroy Iran's nuclear infrastructure. It is implausible that Iran will not retaliate. A cycle of attack and counterattack seems more likely, which will prove to be an open-ended project for the U.S. military.

Two major interrelated projects have been proposed in Iraq and Syria. ISIL is a major player in the civil wars in both countries, and sets new standards for viciousness, fanaticism and ambition. The argument for containing this threat is reasonable, and the neighboring powers are beginning to see their interest in doing so. The United States should be willing to help, but we know from past experience that too much American involvement will mean both too little local action, and too much grist for the propaganda mills of our enemies.

The United States should not be "on the offense" as many suggest. Rather, we should help others contain the ISIL threat, and wait for these fanatics to make mistakes that further alienate them from the region, which they are doing. Though ISIL's treatment of its captives is horrendous, we can already see that President Obama's instinct, which has been to shore up defenses and wait for opportunities, is being vindicated.
