Some aren’t because they are concerned about Netanyahu’s government not doing enough to release them. Others have said they support the need for war previously. I do not envy them and sympathise with their concerns, and am not a military expert so I am not going to say they are wrong in their worries over the strategy.
If the hostages are released it removes a large pretext for war, so without it it increases the chances of the war ending, certainly with international pressure. While there are still hostages conflict doesn’t really stand much chance of going away.
