Yes. The terms were harsh, but ultimately both parties agreed to them. A negotiated settlement.

Note also how the reality is slightly more nuanced. For example, Hirohito remained in power and all members of the Imperial House were spared criminal prosecution. That was an unfortunate but necessary compromise. If the world was fair, they'd have hanged them all, just like much of the Nazi establishment.

This also why at one point Japanese officials, basing themselves on the Potsdam Declaration, argued to MacArthur that Japan's surrender had in fact been contractual and conditional. Obviously he told them to go fuck themselves, and because the country was by now occupied, there wasn't exactly much they could do about it.

It's unfortunate, but this is almost certainly what will happen with Russia. A ceasefire will be agreed under conditions both parties accept. The better Ukraine does, the worse the conditions will be that Russia is forced to accept. With a bit of luck, the conditions will be so bad that Putin falls out of a window and is replaced with someone slightly more sane.

Once the ink is dry, the west will hopefully arm Ukraine to the gills, perhaps institute a no fly zone, give them NATO membership or something approaching it, etc. etc.

But before that happens there will still need to agree to a ceasefire, hence all wars end with a negotiated settlement, unless you engage in genocide.
