I imagine there's competing interest where what ever could be mutually gained by Russian and Trump colluding for the Presidency can be gained in spite of war/military conflict. There's probably a tipping point, however, that whatever is mutually desired isn't worth a competing cost. For instance, if what Russia wants is looser sanctions, at some point, they may realize Trump won't be able to deliver that, or much of anything else. Should that happen it will be interesting to see what Russia decides to do going forward (perhaps releasing what dirt they have a Trump).
