Honest question: what was Hamas' long-game with respect to kidnapping Israelis? Did they think Israel would just negotiate rather than retaliate?
It just seems crazy to me given the power imbalance. A cynical part of me suspects that things are playing out exactly as some evil strategists hoped they would, which, given all the children dying, is super-depressing.
I've heard it suggested that they didn't expect to get as far as they did into Israel and they barely expected to get past the border wall. If that's the case they may not have planned what to do when they did and so there may be no grand strategy behind some or all of it.
That would make a lot of sense. Since Israel has blocked numerous other attacks in the past, Hamas likely expected a similar response, not a complete lack of one from their very apparent and out in the open preparations for the attack.
