Why declaring war to Lego would boost their happiness?

[OliverFA]

It has been stated at several posts that declaring war to Lego would boost their happiness.

This is not the way in which war weariness work. At least that I know. So, I'm very confused about this.

Could someone enlight me about why this would happen?

By the way, even if that's true, I don't change my mind about declaring war to them. The sooner we do it the sooner they will start getting unhappiness

If another civ declares war on you, you get a happiness boost for a time. This is temporary, however, and war weariness will set in as long as that civ is in a representative Government. I don't know if this boost has been studied very thoroughly.

Here's my understanding of it:

If you are declared war on while in Republic or Democracy, It's 5 turns of improved happiness, 5 turns of normal happiness, and then war weariness sets in.

By contrast, if a Republic or Democracy declares war on another, they immediately start the 5-turn clock under normal conditions before war weariness sets in.

My understanding is that the timetable can by expedited and the severity of war weariness can be exacerbated if you lose a number of units outside of your home territory.

Since all of Lego's units are away from their home territory and they'd be attacking Gathering Storm, they'd immediately start the clock on war weariness and any units they lose would contribute to exacerbating the severity of their war weariness.

The oddball is what impact RP Team declaring war on Legoland might have. If we declared war by signing an in-game 20-turn military alliance with Gathering Storm against Legoland, I'm not sure if that's any different from us just outright declaring war on them. Since Lego would already be starting to count toward WW from the GS war, I'm not sure if they'd get a temporary 5-turn improvement courtesy of us joining the war or whether our entrance would be meaningless.

What is true REGARDLESS is that eventually, through time and/or lost units in foreign territory, war weariness maxes out at a rather uncomfortable level. For as long as you are at war, it never goes away. Even if you end a war, it will only start to dissipate and will jump right back up if you redeclare war before it has a chance to dissipate (though the level it jumps back up to is determined by how long it's been since the war, as the game keeps track of WW whether you're at war or not, only APPLYING it if you're at war and in a representative government).
