If the hackers were from China, Germany, or India, would it have mattered?
A group hacked the DNC with the intention of airing the DNC’s dirty laundry. This hack was done from outside of any governmental oversight and without approval by any arm of the US government.
Unless you can prove that the published data is misinformation, then the nationality of the hacker group is irrelevant. On the contrary, based on the panic behind the hack, it seems that the US owe Russia a debt of gratitude. If, as you and others assert, it was orchestrated by the Russian government itself.
Of course, you have yet to provide any concrete evidence to any Russian involvement.
