you see, what this user is saying that the Mexican cartel, a powerful, transnational organized crime syndicate, primarily involved in drug trafficking but also other crimes like extortion, kidnapping, and money laundering, operating with significant violence, complex structures (drug lords, lieutenants, hitmen), and influencing politics through corruption and intimidation. They control territory in Mexico, wage brutal turf wars with rivals, like Sinaloa vs Gulf Cartel, and supply drugs to North America and beyond, could beat the entire roman empire, a vast ancient civilization centered in Rome that grew from a republic into a powerful autocratic state, ruling the Mediterranean, Europe, North Africa, and parts of Asia for centuries, known for its advanced engineering, law, military, and lasting cultural influence, eventually splitting into Western and Eastern (Byzantine) parts, with the West falling in 476 AD and the East enduring until 1453, at its peak which was at 117 CE lead by emperor trajan, if they waged war on eachother.
The reason why The mexican cartel would win the war is because of the sheer gap of advancement. While the romans uses swords, shields, and spears, the mexican cartel has weapons of mass destruction that could take a life by just squeezing a small trigger. Its like bringing a gun into a knife fight
