Take it as you will, but time will tell.
Well, time has already told...Trump has a long list of non-supportive Russia actions....which is why your post was largely inaccurate.
I'll add (as I've said before): Being on non-combative terms with Russia is an objectively good thing. Their nuclear capability is still significant, even as their conventional capabilities wane.
We don't want them to keep getting comfortable w/ China. That is really, really bad.
So, even as bad (really, really bad) as Putin is...anything we can do to affect the Russia/China relationship is a good thing. If that means we can keep peace, increase economic opportunities...that's good for everybody.
What if we make deals w/ Russia that are subjectively better than whatever they're getting from China? What if we are not making Russia feel so threatened, they feel forced to side with China? What if we can make Putin feel secure enough, that he doesn't feel the need to expand borders?
What if, what if, what if????? Peace? Prosperity? China kept in a corner?
The world isn't perfect. Sometimes, you have to maneuver your adversaries into a corner of your choosing. The US has tremendous economic power that we can use.
