Israel now faces a huge dilemma and I believe Hamas has played the one card it had.
The release of hostages now means it is clear that Hamas is willing to release hostages and I presume the price will be a stall and eventual stand down of a ground incursion into Gaza.
Israel backed by the US and the UK have vowed to destroy Hamas and there is a huge army waiting on the border poised to go in. Biden has proclaimed 'we will win'.
How does Israel react now? Can it afford to somehow back away from a ground offensive and allow Hamas in some form to continue to govern the Palestinian people ?
I can't see any easy answer but I feel now Hamas really did know what they were doing taking hostages.
