Trump wants the Nobel Peace Prize, and it's not unreasonable to think Putin has convinced him that it can be "arranged" - so he doesn't care what has to be destroyed, or who has be killed, for him to get it.

The strategic objective - The Big Move - involves dividing up the world into three spheres of influence (ie: ownership). Russia gets Europe and the Middle East, China gets Asia and the Pacific, US gets the whole western hemisphere, and we'll either divvy up Africa, or (more likely) we'll duke it out over that turf later.

Another attempt at world conquest seems to be well underway.
