So Trump, (Putin's BFF) now stands up for humanity for the good of humanity? 
Not likely - I can't but think the two of them are just playing a long game according to pre imagined and defined goals.
To date there is nothing that Trump has done that is overtly challenging to Putin's stature in Syria and Ukraine - beyond any predictable rhetoric, if the USA stops short of significant military action that directly threatens Russian interests, well there's the proof and there's his intended diversion away from gross incompetence as per the Peter Principle. 
Cutting through all  the noise, it seems that neither Trump or Putin will ever resort to anything which is not mutually self serving.
