Regardless, a little history lesson. One of the things Obama ran on was that the United States policy towards Russia was needlessly antagonistic due to the influence of evil neo-conservatives. Hillary went so far as to buy a staples "Easy Button" and present it to the Russian diplomats in her fist meeting with them afterwords... The same HRC that the Russians just mucked with massively during the last election.
I've really come to the conclusion given their support and attacks against both Democrats and Republicans, White and Black, liberals and conservatives that the current Russian government doesn't care about helping a candidate - they want to destroy the civil fabric of the United States.
So yes, enabling dictators to gas their own people, encouraging race riots, and attempting to subvert Democracies by interfering with elections are Acts of war.
