If Russia were to bomb the vaults holding the B61 weapons would it result in nuclear detonation of those weapons?
No.
No.
It would not. Those types of weapons cannot go off by accident. There is a specific chain of events that have to occur, and they cannot occur, even if the bomb hits concrete from 50,000 feet.
If there is an attempt to grab those bombs, I would fully expect to see that area carpeted with nuclear weapons tout de suite regardless of who is there, including our own personnel being trapped there.
That would be an awful choice, but I believe it is the one we would have to make.
But as another Freeper pointed out, the people making that choice in our own government have since stopped being “we”, and are something else, if their actions are any indication. So that isn’t a given any more.
No.

From what I know I believe it would take at least an atomic bomb to set off a hydrogen bomb. Someone else could likely confirm or correct me on that, tho.
NO. Our nukes can't go off unless properly armed by NCA. Proper criticality of a nuclear explosion is a VERY complicated an precise series of events. Interrupt one and nothing happens.....C4 might go off, but not the nukes. It would be messy, but not atomic or thermonuclear by any means.
