The Euros could use a few Valkyries right now. Really pissed ones.
They would melt before an Islam powered by a gate of hell that the Lord ordered may be raised.
We do have one thing in the bible that it says the gates of hell won’t prevail against. And it is powered by that pesky Yahweh, who disdains self effort but will reward those who seek to love Him as a Person (not as a giver of superficial external morals by which men glorify themselves).
Besides. the Valkyries were the cleanup squad for dead warriors. Lots of showy tribute, but are those warriors fighting? I’d sooner bet on a literal living Lord.
