What distinguishes the nuclear capabilities of different nations within the nuclear club?

The nuclear capabilities of various nations differ markedly in terms of their stockpiles, delivery systems, and strategic doctrines, defining the landscape of global nuclear politics.

Countries recognized as part of the nuclear club, such as the United States, Russia, China, France, the United Kingdom, India, Pakistan, and potentially Israel and North Korea, exhibit distinct characteristics in their nuclear arsenals.

• The United States possesses advanced submarine-launched ballistic missiles, with individual submarines containing warheads that carry immense destructive power—far surpassing the total destructive capability of all bombs used in World War II.
• Russia's nuclear doctrine includes the Dead Hand automated response system designed during the Cold War, which remains a significant concern due to implications for human oversight in nuclear decision-making.
• North Korea's limited nuclear capacity primarily hinges on its missile development, which is still deemed unreliable, thereby complicating its status within the nuclear community.

Overall, understanding how these nations differ in their nuclear capabilities highlights the complexities of deterrence and arms control strategies employed on the global stage.
