Humans would simply build a bomb so terrifying, it would make the Hiroshima and Nagasaki explosions look like grenade bangs. One for each major city.
Sonic Rainboom or not, I don't see how Ponies can beat humans because they don't have guns, nukes, bombs, grenades, bazookas and I could just go on and on.
Also, in the world wars, technology developed very fast. That was because it was war. If the humans planned to invade Equestria, they'd definitely come up with some more terrifying WMD's.
i just want to say bazookas and horrible and out of date. A more tarifying rocket is the gavlen
Conjecture on a hypothetical human invasion of Equestria?
