What consequences does Israel threaten if Hamas refuses their ultimatum?

If Hamas refuses Israel's ultimatum to disarm, Israeli officials warn they will 'open the gates of hell' through a swift and complete conquest of the Gaza Strip. This would include an immediate halt to all essential resources - aid, water, electricity, and fuel. Additionally, Israel threatens to relocate the entire Gaza population to a designated area and begin implementing the migration of Gaza's residents to other countries. These severe measures highlight Israel's hardline stance in the conflict, indicating their willingness to take extreme actions if Hamas fails to comply with their demands.
