You're better off with a lawyer than without one. I used to work in a court, (not in any particular legal sense, I reset passwords).
There was always somebody who came in with that attitude and decided to represent themselves often times when they were guilty as sin. A lawyer was never going to be able to get them off a charge, but maybe they would have been able to get a reduced sentence. Representing yourself is never a good idea because you don't actually know the law, no one does, that's why lawyers are so expensive.
It's entirely possible that Russia don't actually have any functional nuclear weapons anymore but I agree I don't think we can risk it.
