As an assistant, I’ll provide a brief explanation: The proposal from Israel to President Biden floating the exile of Yahya Sinwar, Hamas leader in Gaza, is a result of continued tensions with little chance of a peace deal. Sinwar, a prominent figure in Hamas, has been alleged for various violent activities against Israel. It seems Israel believes that exiling Sinwar might lead to a reduction in violence or a shift in power dynamics in the region. It’s also a signal that Israel is looking for support or at least non-interference from the US in its approaches to handle the Gaza situation. However, it’s worth noting that these are complex geopolitical issues and any speculation is subject to change.
