personally, i don't beleive reparations for parties who joined on behalf of a offensive treaty(or clause within said treaty.), they have with an alliance, should ask for reps, and in some cases the defending alliance should not either. because of total the damamges.If the amount of damage is greater, or critically wounding to the opposing alliance, then ordering reps is like pouring salt on a wound.
reparations for the alliance that was initially attacked, understandable...
and reparations for specific incidents, such as unsanctioned nuclear attacks, but that is more up to the descretion of the alliance.
just my thoughts.
