What is the primary concern regarding unauthorized access to nuclear weapons?

The primary concern regarding unauthorized access to nuclear weapons centers around the potential for detonation or malicious use. If an individual or group gains unauthorized access to nuclear weapons, there is a significant threat that these weapons could be used for devastating purposes, such as terrorism, warfare, or coercion. This concern highlights the importance of stringent security measures and protocols surrounding nuclear arsenals to prevent such scenarios. The consequences of a nuclear detonation in populated areas or the use of a nuclear weapon as a means of political leverage could have catastrophic impacts not only on national security but also on global stability and humanitarian conditions. Moreover, the potential for a rogue state or non-state actor to harness nuclear capabilities increases the urgency of strict access controls and monitoring. Overall, focusing on preventing unauthorized access directly addresses the most critical risks associated with nuclear weapons.
