Former President Obama did nothing except order the expulsion of 35 Russian diplomats thought to be involved in intelligence gathering, closed two Russian compounds, and laid down economic sanctions. He also approved covert counter attacks to plant cyber weapons against Russian infrastructure.
Other than that he did nothing. Yes, he kept it quiet because he was worried that exposing it would be seen by Republicans as a political attack on their candidate, since it was clear that Russia was trying to aid the Republican candidate.
And Trump didn't refuse to admit it initially. He refused to admit it for nearly a fucking year. I love your double standard for expectations.
They didn't use speech. They used cyber attacks to gain unauthorized access to American companies and private information. That's not using speech like they do with their state sponsored propaganda arm news channel, RT. This was a hostile cyber attack clear as fucking day.
Rubico was a 4Chan moron who hacked Palin's Yahoo account emails. He wasn't state sponsored and he had no associations with intelligence agencies from a foreign nation. It's no different than a private citizen attacking someone vs another nation attacking someone. One is an illegal action from a citizen and the other is a hostile attack from a sovereign nation.
