No we don't.
"Deter" Russia?
From what?
At the rate Western Europe is going, it's going to be overrun by islam within fifty years, probably irrevocably. Some countries may fall even sooner.
The Russians, of all people, seem to stand up to the muslims well enough (at least in their own lands) when terrorists strike them.
If Western Europe is in the process of collapsing to islam, perhaps the Russians will invade and drive the muslims out.
Would WE do that?
