Current U.S. and Western military doctrine says that the price of civilization and freedom is eternal vigilance, and therefore all the Western powers maintain substantial armed forces technically ready for combat at any time. None of course does this more enthusiastically than the United States of America, who invests a huge fraction of its national pride and identity solely in the might of her military and her nuclear arsenal. In response, the other great powers of Earth must maintain their own forces, striving to maintain some sort of balance with the Western military hegemony.
And then there's the most notable client state of the West, Israel...but that's a tale for another time.
The world has been tending this way for a while, despite spasmodic attempts to dial it back on the massed armies and move towards a more harmonious and diplomatic relationship among nations. The League of Nations and the United Nations must both be ruled failures. Currently the U.N. is virtually ceremonial in many respects, actively harmful in others. Since World War II the United States has never really left wartime footing—there was too much money in keeping the factories churning away at top speed, so the U.S. figured out ways to maintain a warlike posture. Decades of right-wing propaganda have assisted in cementing the U.S. and the West in a permanent Orwellian "war is peace" posture. Conventional political wisdom says it's madness to consider anything else...which is ironic, considering that MAD is precisely what got us here, the cloud-cuckoo logic of nuclear brinkmanship.
I'm no expert in these matters, but I have a friend (here in the Pnictogen Wing, one of our introjects) who knows a little about them: Jeanne d'Arc, who first came into the system as she appears in Fate/Apocrypha (see 2nd picture) but then decided she preferred to look as she does in Jacques Rivette's monumental five-hour movie Jeanne la Pucelle. And yes, I've seen all of it, more than once. Jeanne's a bit tickled that I kinda...fell for her in her Fate/Apocrypha form, blonde and pig-tailed, even though all historical accounts say she had short dark hair. I vaguely recall that Jeanne once told me that she was willing to manifest in whatever form was suitable to the occasion. Her blonde pig-tailed appearance in Fate/Apocrypha derives from the young French woman who consents to host her in that series, for what it's worth.
Jeanne d'Arc considers herself to be no saint, only a humble French soldier, and here's the key thing: she grew into the rôle. She arose from nowhere, knowing nothing, when her country needed her. On the job, as it were, given the task of saving France, she learned what she needed along the way. Heaven made the way clear for her...until her job was done, and then sadly Jeanne found out what happens to heroes in this cruel and wicked world of "the West". But oh, how brilliantly she shone before then! She was no sort of professional anything; she was a God-fearing peasant girl, and she went to war and saved France and gave the English a right kicking. It's always good when England loses, but it's especially sweet when a French peasant girl administers the beatdown.
I consider the mere existence of Jeanne d'Arc to be a rebuke to the standing-army theory, the idea that a nation can only survive by arming itself to the teeth at all times. If the United States were truly as righteous as all the right-wing God-botherers say, she would not be so frightened, so terrified of "terrorists", so ready to make preëmptive war at the slightest provocation. It's like how Elon Musk or Donald Trump, both "men of the people" according to their admirers, can barely appear in public at all, always requiring the very safest of venues and a posse of mercenary thugs. The fans try to have it both ways, both declaiming about Musk being one of the people and hollering about how everyone wants to kill him. But if Elon Musk were truly beloved, truly the friend of humanity, he would not need his standing army.
In the hour of need, heroes DO arise sometimes. It's happened before. Jeanne d'Arc happened.
I am grateful for everything she's ever done to help us all out. My eternal gratitude, Jeanne. Bless you.
