Well, just take into account that you have bargaining power with France (you can promise to help out BBB on condition of taking 3-4 colonies from Spain - Cape Verde and 2 provinces in the new world are most important) and Spain. You can use this threat to take concessions from Spain. Austria as a guarantor currently works in your favor.
Will see what happens, will most likely not make any radical changes the closest years. But who knows how the world looks in a century from now. Keep in mind, I try to avoid being too dishonorable/backstabbing simply due to that having a reputation as a player worth being allied to is advantageous in the office meta game.
Also, please, capture gold in Kilwa and Morocco![]()
Thanks for eye opener, yeah will probably do.
