Man Japan can't really catch a break can it? When it's not foreign wars it's civil wars making things complicated, hopefully this one will be short and not too destructive.
I think it's unlikely, especially because a stronger and with better finances France would seek to take control of the region, especially because their Alliance with the Dutch republic was brought to a end sooner than OTL so France will be pressing them much more in order to get all the Catholic regions in the Netherlands under their thumb.I defo don't even with what's left being mostly Walloon land. France is already strong enough, and it'd probably just make France stronger if that's the case. If the stadtholder can get the Catholics and protestants to work together (a hard feat considering it all) this Dutch republic will be a lot stronger tho.
