President Obama made a statement on the recent indiscriminate attack on an open-air market in Mariupol, Ukraine. At this time, the incomplete reports list 30 as killed and as many as 100 wounded, one of many terroristic acts.
He declared the culpability of Russia and Russia's proxy organizations, the Donetsk People's Republic (DPR) and the Luhansk People's Republic (LPR).
While the Department of the Treasury has already sanctioned individuals, there remains one untried option which would meet Pres. Obama's twin demands of neither bankrupting Russia, nor placing American military men in harm's way.
The president should use the power of Executive Order 13224 to declare these Ukrainian separatist groups to be terrorist organizations, and to penalize them as fully as possible under the law.
