The use of nuclear power has a double effect that can undermine power generation and increase leverage on the energy front while also creating fear of nuclear weapons. This poses challenges for countries worried about their neighbors' nuclear capacities and maintaining strategic nuclear balance, making it important to negotiate with other nuclear powers.
The military actions near the Chernobyl nuclear power plant cause a double effect, undermining power generation and scaring people about the use of nuclear weapons, causing fear from the perspective of nuclear power and increasing energy leverage. There is an added effect of cutting off Ukraine's power supply by shelling the Chernobyl plant and the sarcophagus and putting it at risk.
The United States and the United Kingdom have an obligation to step up and help maintain the strategic nuclear balance for countries like India, Pakistan, South Korea, and Japan. This duty goes back to when they promised Ukraine that gave up its nuclear weapons in 1994, to ensure territorial integrity and sovereignty would remain intact.
