Yeah. Washington DC doesn't have some magic key that is the only thing that can launch or detonate US nuclear weapons. All the US executive branch has are codes that the nuclear weapons armed crews of the US military use to confirm orders are legitimate. All of those crews are able to launch or detonate their weapons. This is necessary because when the US military goes to a high defcon level, if the US nuclear command and the executive branch become unresponsive, doctrine calls for local commanders to start launching nuclear weapons without orders on the assumption a decapitation strike has been made against the US. Russia and the UK also have similar fail-deadly nuclear doctrines.
