Is good for absolutely nothing. The song was right about that. But we’re not talking about that song, we’re talking about something that actually happened.*
When we last left our heroes (or villains as some might call them), The Nation of New York had started a war with the United States of America (Minus New York City). Most of the bridges connecting Manhattan, Brooklyn, Queens, Staten Island, and The Bronx had been destroyed months ago in separate acts of aggression, but now things were getting bad. The aircraft carrier that was dispatched last month was loaded up on refugees and sailed out of the harbor prior to any major conflict, but they didn’t go far. The President, knowing the options on the table transported them down the coast to Florida, he claimed it was the best place for them. In reality he was getting them as far away from the blast zones as possible. While it was unlikely that much would spread past New Jersey, he couldn’t take the chance that radical New Yorkers had traveled far enough out of state to cause problems.
Luckily for America, they have the world’s most powerful Navy, and another aircraft carrier was sent up to collect more refugees. However, the hurricane prevented docking. All for the better because of the attack that happened on the city. Somehow, the rebels had gotten their hands on surface to surface missiles and had mounted them atop most of the tallest buildings in the city. (As luck would have it, they left The World Trade Center alone, they felt that those towers acted as a nice shield masking the true location of the launches).
The RNYs took potshots at the carrier group, never really doing any damage, but causing headaches. After a week of non-stop attacking, the President played hardball and ordered a response.
Things did not go well.
The City Corp Building was demolished. To the average RNY, this was motivation enough to surrender. But the ruling class had too much pride, or more likely too much stubborn New Yorker in them to give up that easily. They hunkered down and spread out. The last of the known tunnels out of Manhattan were used to spread themselves and their explosives wide. The President was not going to start an urban war on the streets of the most famous city in the world, so he had the Air Force keep buzzing the building tops trying to demotivate the populace. Unbeknownst to them, no one was in those buildings.
Where they went is still a mystery, but once it was discovered that the island was nearly empty, all bets were off the table, bad things were about to happen.
*in an alternate reality, duh.
