Dear Princess Celestia,
I just wanted to tell you that I heard your speech over the radio announcing the war to liberate oppressed peoples everywhere, and it was the most uplifting thing I’ve ever heard! I thought your reasoning and logic behind our first war in over 200 years was absolutely flawless, and you are most certainly right about our cause being morally just. I don’t think there was a dry eye in the library when you described the horrible conditions those poor Diamond Dogs live under, or the plight of Saddle Arabia from their “tyrannical and morally bankrupt” dictatorship of a neighbor. Equestria needs to be more involved in making the world a better place to live in, and you laid it out with such wisdom and honesty, I could have sworn I heard everypony across the nation, nay, across the entire world rise up and cheer you on in your quest for a better world. However, there is something I want to ask you, and I hope you’ll please consider it carefully before potentially rejecting it. I would like to humbly ask you for permission to enlist.
Please hear me out! I don’t want to join for the glory, or because Shining Armor is already in the military, or because Rainbow keeps telling me I should to prove my loyalty to Equestria. It goes much deeper than that. I want to join because I genuinely believe in Equestria’s ideals of freedom, love, and tolerance, and my sincerest wish is to help us spread those ideals around the world in peaceful manner when practicable, but in war if necessary for those rulers too blinded by their own power to see what’s good for their subjects. I realize that joining the military is a big commitment, but I believe myself more than capable of handling the rigors of military life. After all, basic first-aid on the battlefield can't possibly be harder than saving Equestria from certain destruction three times.
Even with all that, I realize you have many valid concerns. What will Equestria do without the Element of Magic were she to be killed? What if she’s not ready for the trials of war? Well, I can tell you my mental health is as solid and robust as it’s ever been, and my physical abilities have been vastly increased due to assisting AJ during apple-bucking season. I’m going in as a medic anyway, and the international rules of warfare expressly prohibit the killing of medics. But we both know that’s not the whole picture.
I know from your speech that the long and winding road we must trot will be full of pain, despair, and death, but I am not a filly anymore. You told me once that the best thing about Equestria was the fact that everypony, no matter how big or how small, can achieve their dreams through hard work and determination, and so I must beseech you now to allow me the same opportunity. My morals will not allow otherwise, and I’ll never forgive myself if I do not at least try to change the world for the better. I don’t even want to kill any other creatures; I always intended to join as a battlefield medic. After all, what better way to assist the war effort than to make sure our wounded soldiers can get back up and fight on?
Spike’s starting to whine that I’m making this too long, so I’ll have to end my plea to you here. I know I’ve given you a lot to think about, so just please reply as soon as you are able. Wars don’t plan themselves after all, and I don’t want to be an unnecessary distraction to you.
-Your Faithful student,
Twilight Sparkle
