A large diplomatic envelope officially used by Konohagakure no sato would arrive on the desk of the Kazekage, it would have upon it:
TO THE LADY KAZEKAGE
Greetings and all due salutations Uzume Sakizaki Lady Kazekage,
It is not without diligence to say that our countries suffered pointless conflicts in the past, and that merely trivial steps towards that peace have been made to resolve such conflicts. There is a great deal that Konohagakure and Sunagakure have squabbled over in the past few decades. Many lives were taken without due thoughtfulness to diplomacy. Diplomacy that could mean security for our peoples, the opportunity for which I hope has not yet been squandered by the mistakes made by our predecessors.
In light of such due diligence and diplomacy that I extend this olive branch to you, my esteemed colleague, and leader of Sunagakure no Sato.
That Konohagakure may be called upon to defend the Land of Wind from outside invasion, and that Sunagakure may be called upon to defend the Land of Fire from outside invasion. Provided that neither village takes overtly aggressive action to cause the endangerment of their country by invasion. That such actions may be known as a Mutual Defense Agreement between the powers that be of Konohagakure and Sunagakure.
Though it would dishonor the loyal service of the fallen to ask you to forget their sacrifices for both our nations, I humbly entreat that you view such sacrifices as leading us to this position, a position in which we take hands as allies to secure a more prosperous future for both our villages.
Eagerly awaiting your prudent response,
Uchiha Akira
Lord Hokage
