I think that might be a step too far, rather I'd guess the US just knows the Russian systems very well. The success of the latest campaign against Iran shows that too, and if anything they learnt even more from that.

Either way, although Trump might every now and then be a bit too friendly with Putin, but a) cooperation at this scale and b) the bad looks and damage to Russian investments I think makes it seem unlikely. Putin doesn't stick his neck out for others unless it serves him. I'm not that well read on the Russian involvement in the area though...
