"our intelligence services concluded" [Paraphrasing] 'its highly probable the Russians were behind the hack' They may well be right, however it is still speculation without unquestionable evidence to definitively conclude the Russians are responsible.

IF? I can't say for sure Putin necessarily supports Trump.  Maybe? Maybe not?  At best Trump happens to be the spoils or current candidate byproduct alterative of Putin's unquestionable HATRED of Obama, Hillary, & of course the USA.

Seems to me that Russia & other foreign powers who are anti-America would benefit greatly from a Hillary presidency.  [1.] Hillary is nurtured by foreign powers by the constant threat of blackmail. [2.] Hillary in office will most likely create a constitutional crisis from day one. [3.]  Thus a Hillary presidency will be the most ineffective in history, leaving the USA & it's interest even more weakened in world affairs to such a degree Russia and others could do as they please unopposed.
