"There is always talk about defusing tensions and preventing a potential war in Donbass.  We hope that political wisdom will prevail in Kiev, the case will not take a serious turn and provocative actions (against Luhansk and Donetsk) will still come to naught.

The constant repetition of US calls to Russia to "abandon aggressive actions" devalues ??these statements of Washington -

A possible appeal of Kiev to the United States to use cruise missiles at Donbass targets will push Russia to recognize the DPR and LPR with the subsequent introduction of Russian peacekeepers into their territory.

In the case of the use of cruise missiles from the destroyers USS Donald Cook and USS Roosevelt of the US Navy from the Black Sea through the territory of the DPR and LPR, American warships may be destroyed. Thus, Russia will defend Russian citizens.
