I think people are often "ok with it" until it starts to go badly. That's not to say people agree with it, but they don't think strongly about the matter, so if the leaders say this is necessary, they go along with that, or they don't think they can make a difference so they just try to ignore it. Until things go badly.

When Japan started invading everywhere nearby, most people didn't like it. They asked why, they raised anti-war points, they rejected the need for violence or death. But government propaganda started up, about how this was necessary not only to secure Japan's future, but to protect all these countries against "Western imperialism". Hard core ring-wingers bought it, as they always do (as the MAGAs show us now), left-wingers remained completely against it, but the people in the middle, they kind of threw up their hands and said "whatever. Nothing I say will make a difference, so whatever," which in action basically reads "I'm ok with it". The gov took care of the left by making anti-war talk illegal and throwing enough people into prison that the rest were silenced. It wasn't until the war turned badly for Japan that the middle and right both became very much against it.

I think it's mostly the same in any country. You can see a similar pattern in Germany and Italy during the same time period. And you might be seeing the same thing play out in the US. Though hopefully there it doesn't go as extreme as in the other cases.
