Why can we not enter war to protect CNs?

[Camara]

-5 stab hit for truce break DoW really really really hurts tho Especially seeing as how at the same time this was going on my ally Austria drug me into a Europe-wide religious war.....

Don't they have allies you can DOW to call them into the war bypassing the truce?

I had a truce with the attacker on my colony and I was still able to enforce peace.

On the wiki, there is four condition for enforce peace with with the exception of cn :"If the defender is a colonial nation of the enforcer, only the last two conditions must be fulfilled and the enforcer becomes the warleader if the attacker refuses the demand."

So you can defend your colonies even with a truce and you don't even need to have positive Relation with your cn.

I tried it in my game, I became a cn Sicily, ally Spain, broke the alliance, attack cn from SPain, Console tag Switch Spain and I could enforce peace even with low relation and truce.
