First off
Take your hands off your ears and stop shouting
Nya....Nya...Nya....I CAN'T HEAR YOU
Wow, that's it? That's all you haters got? Pretty embarrassing.
Trump's response to all this has been embarrassing
Calling claims false without any substantiation, screaming ignore this....nothing to see here
Calling everyone else a liar
He is like a child getting news he does not like
Yeah we get it, you hate Donald Trump. But what do you want him to do in response to 'Russian Hacking.' Try to focus.
Initiate sanctions. Engage in covert retaliation. Expel diplomts. Send the message this shit will not go unanswered.
You know, all the things a real president, like Obama, did.
You know, you are almost, but not quite old enough to remember the cold war.
If you had, you would know that two of those things is unacceptable.
During the cold war, this shit went on all the time.
If we take the hypothetical that the Russians actually were involved, which, hasn't been proven, it could just as well have been agents in the Deep State using Russian methods in an attempt to reveal Clinton's corruption. After all, she caused their agents to be killed in Benghazi and Aleppo, that is sufficient motive for their actions. The Russians? They would have nothing to gain (substantially, and everything to lose, if caught.)
Now, if we assume it was the Russians, in the world of espionage, the appropriate response, the proportional response, is, as you wrote, covert retaliation. That has already been done, in both that terrorist act recently in Turkey, and the assassination of the Russian ambassador to Turkey.
So are we done here?
This is an irresponsible policy that is pushing Turkey into the foreign policy orbit of Russia. Not a good move by the current administration. (If they in fact have any control over any of it.)

The other responses that you mentioned would never have even been considered during the cold war, as they are not proportional responses. In the game of spy vs. spy, you keep to the game. If the elites decide to escalate the situation, then clearly, it wasn't the Russians, they are being used as an excuse for an ulterior motive.
I suggest you read this book. . . .
