I think what happened to sour Putin against the USA is that while Obama (and Hillary) claimed they wanted to “reset” Russian relations - his administration was involved in the coup against the Ukrainian government in 2013/2014 (with Soros aid) and added Ukraine as well as several Eastern European countries under NATO. They also supported opposition candidates against Putin within Russia. From the Russian perspective, those are old Cold War type actions against their country. Is it really surprising then that Putin would reciprocate? This is the context which I think is missing from the current hysteria about Russian meddling.
It really is quite hypocritical of the US to be so outraged over 2016 when for the last decade we’ve been giving it to Putin in spades.
I’m sorry I made a subjective observation not related to this article. Late 2010 and 2011 watching the dollar slide. Listened to Singapore news. India, China, and Russia were going nuts about the dollars slide India wouldn’t buy dollars. China manipulated their currency so there exports would continue. Russia was really upset and Putin called the US dollar a parasite currency. I made the observation their petro-dollars value was evaporating and Putin was pissed.
