I'm not saying they should become allies, but "getting along" would be good enough. It would relieve so many hostilities in this world and we wouldn't have to worry about another cold war.
Furthermore, we could coalesce and fight off and eventually destroy ISIS together.
On the one hand Clinton would be open to declaring war against Russia, whereas Trump has repeatedly said he wouldn't and would actually try and improve US-Russia relations.
Are you going to achieve yours?
