(i) to be responsible for or complicit in, or to have engaged in, directly or indirectly, any of the following:
(A) actions or policies that undermine democratic processes or institutions in Ukraine;
( actions or policies that threaten the peace, security, stability, sovereignty, or territorial integrity of Ukraine; or
© misappropriation of state assets of Ukraine or of an economically significant entity in Ukraine;
For example, what are "direct or indirect...actions or policies that threaten the peace, security, stability, sovereignty, or territorial integrity of Ukraine"? Could that be someone writing an article that takes issue with the US policy that the Crimea referendum is illegal and illegitimate? Could it be standing up in a public meeting and expressing the view that Ukraine would be better off with nationwide referenda to determine whether other regions should become autonomous or joined to neighboring countries? What if a Polish-American appears on a radio or television program suggesting that parts of Poland incorporated into Ukraine after WWII should be returned to Polish authority?
The president will probably not seize the assets of Americans in the scenarios above. But he says he can.
