While Hamas is presenting Sinwar's appointment as a significant achievement, viewing it as a demonstration of strength while he hides in tunnels and is wanted by Israel, not everyone within the organization's leadership agrees.
There are considerable concerns that Sinwar’s appointment could cause significant damage to Hamas and even jeopardize its continued existence. Sources who spoke to the Saudi newspaper *Asharq* expressed worry about the appointment due to Hamas’s increasing ties with Iran and Hezbollah, which could lead to a crisis with Qatar and Turkey and possibly result in the loss of their support for the organization.
Additionally, within the terrorist organization, there is concern that Sinwar’s appointment might make him more dominant, turning the organization into a more military entity and less political. This shift could complicate explanations for countries that maintain relations with Hamas, weakening the political consensus that supports the organization from countries hostile to Israel.
An official source in the Palestinian Authority explained the implications of the appointment, stating, "It is clear that Israel will not stop its war against the leadership of the movement in Gaza. Once Sinwar takes over the political leadership of the movement, it will fight any attempt at Palestinian consensus in managing the Gaza Strip."
