As someone pointed out above indeed this is a chess game.
1) Hostages: if we go in we risk losing them. On the other hand Hamas will never free all hostages. At most they free civilians. They will only do that in drip drip stages schleping it out for months. Then they will hold on to soldiers till every Palestinian prisoner is let go. israel will have to settle for some middle ground of maybe getting at least women and children out before any invasion. Its so tough.
2)Yes you don’t want a world war on 3 fronts and so we need to make sure the USA has our backs and do this thoughtfully in a way that doesn’t provoke Lebanon into full scale war. Maybe the answer is just a go little in at a time etc. Till they get used to it. Again tough
3) what to do with the tunnels , traps and everything else set up on the other side? You need caution.
4) You can just go in and kill 500K civillains. Right now Hamas isn’t letting them leave.
There is a thought in me that had we rolled in on day one with force they would have been unprepared even with all that planning. And we could have accomplished alot. But that assumes that we had all the troops ready and all the weapons etc. And we still would have lost alot. This day one scenario is very impractical. And so now once they had a week or 2, you need to be more cautious
Will they go in? Who knows. Ultimately the goal isn’t to go in. its to get our hostages home first and then to decimate Hamas. I think most definitely its wise not to just barge in at this point
