From Ukraine to Syria, the Obama administration has consistently misread Russian President Vladimir Putin ’s objectives and the implications of cooperating with him. This has led to costly failures, but the administration is unlikely to change its approach. Congress need not sit idle too. By enacting new sanctions on Russia, U.S. lawmakers can send a strong signal to Moscow that its continued aggression against Ukraine and growing complicity in a genocidal war in Syria will come at a heavy price.

After Russia annexed Ukraine’s Crimea in 2014, the Obama administration and many U.S. allies imposed sanctions on Russian businesses and individuals. But those measures clearly haven’t been effective in discouraging Mr. Putin’s quest to exert Russian power and influence.

In Ukraine, despite the supposed cease-fire effected by the Minsk Accords negotiated by Germany, France, Ukraine and Russia, Moscow-supported aggression continues in the contested east. Russian troops remain in the region, as an extensive Sept. 14 report from the Atlantic Council documents, and Reuters has reported that new Russian military bases are being built.

In Syria, Mr. Putin, under the guise of fighting Islamic State, supports the Bashar Assad regime, which has used barrel bombs and chemical weapons in slaughtering tens of thousands of civilians, mostly Sunni Muslims—making Russia complicit in, and legally accountable for, these actions. The Obama administration over the past week has hinted that it might cooperate with Russia’s anti-ISIS campaign. Read more »

While Russia’s aggression against Ukraine tramples the United Nations charter, Moscow gets a free ride on its other transgressions of international law. Few have focused, for instance, on how Russia’s military operations in Ukraine violate the 1949 Geneva Conventions. The failure to challenge this misconduct is profoundly wrong and damages the integrity of this whole body of law.

The Geneva Conventions are a great civilizational accomplishment, tempering how wars are waged. For years, they have been transgressed by non-state actors who fight out of uniform, target civilians, take hostages and engage in torture.  But these critical legal norms are far more threatened when such conduct is embraced (in action if not word) by a sovereign state and a party to the Conventions.

The fact that Russian troops operate in Ukraine in unmarked uniforms, or pretend to be civilians, is a significant Geneva violation. States can and do use commandos who operate with stealth and concealment, as the United States did in both Afghanistan and Iraq. There is a fundamental difference, however, between using special forces in an announced armed conflict and doing so while denying that one’s military is engaged at all, as Russia has done.

Moscow is trying to avoid political and legal responsibility for its actions — and Ukraine is not the only place it is prepared to act. Latvian analyst Janis Berzins has analyzed internal Russian military documents describing Moscow’s “new way of waging war” that includes undeclared wars, undercover destabilization, attacks on civilians to create false humanitarian crisis and psy-op operations. Moscow believes this style of waging war could be particularly effective against neighboring countries with large Russian-speaking populations.
