It seems those letters enclose some kind of global strategy according to your words.
Let's skip that pretended refusal to war you've played here for so long. Aurvandil has provoked and has played hard with every realm that has surrounded it. It has profited of betrayal and deflection, and has exploited any imaginable hole in a treaty to its own benefit. It has interfered on the politics and the wars other realms were playing, and it has willingly brought war to the realms it wanted to.
Your complaint has been that once you have "sharpened your swords in the stones of others' Senate houses", you have expected those realms to just nod and sign peace quick as pan, instead of hating your arrogance. Now Falkirk is about to fall, instead of destroying periodically the productivity of your enemy realms, you'll just try to dissolve the members of the Veinsormoot one by one to avoid your armies to face an equal enemy.
"Madina Contingency". I'd really like to see someday how it works on Candiels.
