Not sure about good friends, but I believe that there's mutual respect.
Excerpt:
A hidden video making the rounds online is sending shockwaves through the political world — and giving Americans a glimpse of what real diplomacy looks like.
The clip shows President Trump and Russian President Vladimir Putin speaking off-camera, relaxed and smiling like old friends. Instead of the tense, scripted interactions the media loves to obsess over, this private moment captures something very different: two world leaders who actually get along.
They are much more naturally friends than Putin and Xi. This fact is better for the world in the long run.
