Obama has already established that he may act unilaterally without the knowledge or approval of Congress or the courts. He will get no resistance from Republicans, the States or the Military.
The only question is: will the Russian weapons work as advertised.
If so, Obama will have achieved his goal from his taxpayer supplied bomb shelter. The elimination of White Christian resistance to world Islam and Sharia.
L’il Barack would not dare do it himself, if only because he would not want the Rooskies getting any assassination ideas, but there could be a web of support leading to him. It would kind of fit with the American tradition of trying to fight wars for the Western way via proxy.
... except now, what had been the Western way, the Jihadis have wormed their way into. We is compromised. Bad. It would probably take the willingness of a Trump or a Cruz to tell the presence of such a compromise to begone.
Also I’d say even in such a suicide scenario for the US, that doesn’t mean it’s a Jihadist victory against White Christians, unless present Russians aren’t largely some variety of White Christian. Orthodox church to be sure, and there seems to be little love lost between them and the Protestant/Catholic axis of most of US Christian faith. That could change though. As is said, no atheists in foxholes.
I think even Putin knows that general America is now not supporting Barack’s tantrums, and would tend to go easy on it. However he will not brook Barack rolling a red carpet for Jihadists up to the Kremlin’s door.
It’s not going to be a matter of whether Christ and His believers win... it will only be a question of how.
