Please note: This has no bearing whatsoever on my personal beliefs. It was simply an idea I wished to turn into a story

In the year 2027, Equestria appeared in the Pacific Ocean and established relations with the UN. They claimed they had been brought there by accident, and that Discord was responsible. However, relations quickly began to sour after a failed attempt by five of the six elements of harmony to push their values upon humanity. And, ended altogether when Celestia banned trade between Equestria and the rest of the world. Soon after, started the conversion war. Using her magical barrier she tried to wipe them off the face of the earth. But hope for humanity came in the form of many ponies and others who wished to join them. However, when the night came for them to link up, they found that the resistance had been destroyed before they could leave Equestrian waters. In the aftermath, humanity assumed that all was lost...until a mysterious rainbow-maned pegasus crashed and landed near Jerusalem claiming to be on the human side. However, the agent of the Aman (Israeli Military Intelligence Directorate) assigned to her quickly comes to question her motives.

After the Equestrian invasion and the death of Emperor Amore V at the hooves of the pegasi. His son, Amore VI, seeks to regain his lost territory, but first, he must stabilize his position and restore balance.

However, Pyotr Wrangel, Sergei Mosin, Sergey Markov, Mikhail Drozdovsky, and Maria Bochkareva appear to have other ideas...
