Getting a casus belli

[Brick Slayer]

I know that this is a very nooby question, but how do I justify war goals and get a casus belli in this game? It's very straightforward in hoi4, but in this game I haven't found a good way to do this yet. It seems to me that you can only get a war goal against certain countries when playing as a certain country (like when England wants to make the british empire) or through very specific events like when someone insults you.

So, is there a way to get a CB against any country, or do I just have to accept the aggression points and the stability penalty if I want to attack someone particular?

you go to the nation you want ot make a wargoal agenst, click on "covert action" to build up a spy network.
when you have gotten to 20 worth of spy network you can use that to make a claim on a province. eather by clicking on the fabricate claim button, also in cover action menue, or by clicking directly on a province and there is a button there to make a claim if you have the spy network.
so the 1st claim cost 20, and then it goes up by 5 for each one after that, so 20 for the 1st, 25 for nr 2 and 30 for nr 3...

If you hace borded with someone you can build spy network to make claims on provinces, that will give you conquest CB, the most common one.

Right click target country for Diplomacy screen >> Covert Actions >> Build Spy Network >> Once you have 20 Spy network you can use Fabricate Claim next to it

This will give you claim on one province. Notice that you can only fabricate claims on the countries next to you, not just any country all over the world. You can keep fabricating claims on same country for multiple claims but each will cost 5 network size more.

To start a war you only need one claim, you can take other provinces too in peace deal, not just the one you have claim on. Those you have no claims will simple cost more warscore and cost more to core.

Other "easy" CBs:

- Humiliate Rival: automatically gained, against rivals (has some peace treaty options disabled)
- Deus Vult: last idea of religious ideas, against all bordering nations with another religion
- Defender of the Faith (for Christian and Muslim Religions): If country A shares your religion and country B (pther religion) attacks A you can get (there are more conditions) a CB to attack B (to defend A indirectly)
- Diplomatic Insult: through events or as diplomatic action against you
- Colonialism: when a province of you which has no connection to your capital and is on another continent borders a province which fulfils the same conditions
