Is this what Hamas wanted when they killed and raped on October 7?

Did Hamas and its leaders want/expect an all-out war against them in Gaza after they committed the appalling atrocity on October 7 - a whole year ago today? Huge numbers of their members have been killed, swathes of Gaza have been destroyed, there's almost a full-scale war between Israel and Hezbollah and the world is waiting for Israel to strike at Iran, Hamas's supporter, armourer and financier. Did they work out that this is what might happen and did they calculate that it would, in the end, benefit them in some way? If they did, they seriously miscalculated. The one thing that Israel has shown above all else is that it will never give up until Hamas and Hezbollah, and to a certain extent Iran, have been taught taught a lesson they will never forget or be able to recover from. This is the relentless message from Benjamin Netanyahu. So how could Hamas's leaders, or what remains of them, have thought that committing the October 7 massacre and kidnapping of hostages was going to solve anything vis a vis their future and the political future of Gaza? What they did has brought about the demolition of Gaza and the elimination of their power to rule Gaza ever again. And in the process they have lost their mighty supporter across the border in Lebanon. Hezbollah, too, is now hugely damaged, having seen half of their missile stocks destroyed by Israel. The October 7 massacre was a demonstration of man's inhumanity and Hamas should be regretting it to the end of their days, if they have any days left worth counting.
