Earlier quoted context omitted.
I think it's reasonable to assume that for at least the next few months, you have a strange form of "diplomatic immunity" for attacks in Russia. No jury in the US would convict you, even in the unlikely event someone wanted to prosecute (which would be political suicide here). So, have at it.
Am not from the US but this seems very risky. Is there someone at the government who can clarify such guarantees. Am also curious what are the high level logistics to carry out something like this. Do you seek an untraceable route to Ukarine from US ? Do you unleash a worm like Stuxnet that will eventually cripple all Russian cyber attack infra ?
The idea is that a jury is allowed to make its decision without any outside interference. A jury can acquit a person even it they think the person is guilty. Thus a jury could give you a fee pass on hacking Russian systems, but you'd be relying on them to realise that and then think the moral reasons for acquittal out weigh the legal reasons for conviction.
Obviously courts don't like jury nullification try to prevent it, without harming a juries independence.
So possibly not a good idea to rely on jury nullification as your get out of jail free card.
