How the U.S. thinks Russians hacked the White House

Just curious; if it was known the russkies hacked the White House, why was it not a big deal? Where was Obama and why was he not beating himself in the chest then?

Ah yes... he was friends with Putin then

 

The response of US against the hacking suggested that it's not as deep as reaching nuclear arsenal which is somehow highly defended. What should be the reason why it should be hacked in the first place, to launch nuclear missiles and start world war 3, that would be mostly idiotic, even ISIS would not dare doing that for they will lose the chance of establishing a an Islamic caliphate or sort of. So what Russian hackers are doing is that they only wanted to control politically the US and somehow I could say that they are corroborating with higher echelons of Russia's governance most probably Putin. But one thing's for sure they could hear how Trump speaks but they could never see how he thinks. They are also being used by Trump, and they forgot that Trump is an American not really a Russian.

 

Apparently Obama dropped the ball on computer security.

 

What's Obama's handicap and is it any better than when he was first erected? Just curious, for nothing else is better...
