If Russia is seeking to subvert US elections how should Obama respond?

[Nuclear Unicorn]

Sanctions?

Eject Russian diplomats?

Cyber counter strikes?

Military strikes?

Take matters to the UN for arbitration?

Something else?

[Lanius]

1. Cyber counter strikes

against their government institutions.

[Koinos]

2. Obama has already talked about some sort of proportionate response.

12. Putin already does that

5. Deport Trump and Manafort to Russia?

[allan01]

6. tell them to quit meddling in our internal affairs as they do us.

[Nuclear Unicorn]

8. Would we be withholding the phrase "pretty please" as a note of our displeasure?

[dalton99]

7. Kick Russia out of the banking system

[roamer65]

9. Filter out all Russian internet traffic to the US.

If the Chinese can have the "Great Firewall of China", we can have one too.

10. I'm no fan of the Russians but I can't help but think

such a plan would rely on ISP cooperation, it would be wildly politically unpopular for the government to tell Americans what they can and cannot see on the web, and probably would never withstand 1st Amendment scrutiny.

[DFW]

13. Something else

And he should keep his mouth shut about it, just like Putin has done all this time while meddling in our affairs.

14. I'm sure a response is currently active

The possible nets and addresses are likely under surveillance and related persons have probably have been targeted by everyone from FinCEN at Treasury to the DEA at EPIC. There are probably multiple dedicated satellites, UAVs and human assets snooping in all the right places.

I'm sure no expense is being spared.
