I don't know how you can be that misinformed, but you got it completely wrong. The cold war was restarted by Obama. It's been apparent for years that the US has been trying to pick a real fight with Russia. Libya was under the sphere of influence of Russia, that's why the US organized a "regime change". Same thing for Syria, except this time Russia intervened instead of letting the US fuck over the world. But the greatest win for Obama was Ukraine since it was so close to Russia. The coup was obviously supported by the US, but the US most probably helped it.
There are two main reasons for the US wanting a war with Russia. The first one is, of course, to distract its population from corruption, but there's now a second one, which is far more important : with China getting stronger, BRICS is now a major threat to the US hegemony. If a third world war is not started within 20 years, the US will lose its role as a world leader, which will be catastrophic for its economy.
Contrarily to every other president before him, and most importantly contrarily to Clinton, Trump didn't want to start a war with Russia, but it seems the CIA and the NSA decided to do some politics and to force him to "change his mind".
