Again if Trump had conclusion with Russia what did Russia get out of it?
Well, we know that Flynn, Page, Manafort, Prince, and probably Turmp himself had discussed the Obama-era sanctions on Russia. So it was probably in exchange for getting those relaxed.
Secondly, it achieved Putin's goal of sowing discontent among the Western democracies who were a united front against Russian aggression. By hacking our election, the British elections, the Brexit vote, and ongoing Active Measures in Germany, France, Holland, Hungary, and the Baltics, Putin is able to achieve with a small group of hackers what 80 years of the Soviet Union's arms build up couldn't; undermine western democracy. And boy, has it worked. Every time a nation elects an erratic right-winger, Putin gains influence. His stated goal is to break apart NATO (which is why Trump was talking about it on the campaign trail) and the EU so they cannot form a united front against him, economically or militarily, as he tries to cobble together the former Soviet Union being the ex-KGB Stalinist he was before the wall came down.
