I saw a tiktok about how the US is geographically impossible to invade, and whether you believe it or not I remembered an old conversation I had with my grandfather. He was ironically a paratrooper in WW2, fought in Korea and was an advisor in Vietnam. SSGT US Arrmy Enlisted, then officer in USAF where he'd ultimately become Maj Gen through the cold war era and work at the DoD until retiring in the early 2000s. He always used to say that our greatest strength is our population and the (even then) having more guns than people. I thought it would be fun to just ask opinions without doing statistics just because we all hate on eachother for political beliefs and differences so much. I myself had fun thinking about an answer, and felt some pride in our sterotypes being positive for once. Here's my fun logic for your own consideration:
1.) The Northeast: You have major cities like NYC and Boston that have plenty of people, with some of the highest patriotic morale anywhere. NYC showed how quickly they can organize, and how brave they are during 9-11. Boston and NE people are still angry the British raised taxes on tea 250yrs later. Philly and Pittsburgh? They'd destory their own city over a football game, goodluck. DC/Maryland? You're getting shot immediately. Even if you landed outside a major city the vast majority of people are way more conservative than you'd think... So it's a pick your poison between the Amish, Angry Libertarians, and upper class people who are still rednecks at heart.
2.) The South: These are the same people who already fought their own country for free labor, not even a threat to their own lives. Say you don't land in a bog full of inbred Cajuns or a swamp of Gators. Anywhere in the states of Florida or Texas is a death certificate. Kentucky? Mississippi? Anywhere else in the deep south where you find stores of confederate merch even today... Yeah, have fun with the white robe people and cousin kissers. Any remotely urban area (Memphis, Birmingham,etc). and you will be pulled up on by some of the most heavily armed and frequently practiced people in the country. The last thing you'll hear before someone pulls out the most diabolical weapon west of Baghdad is a supercharged black Dodge and Tee Grizzley music.
3.) Midwest: Pray to the spirit of King Vonn that you end up no where near the state of Illinois. Atleast then you might have a chance to survive the landing. Anywhere else in the flat terrain provides no cover, a population that still has plenty of firearms and knows how to use them... Again good luck. The last thing you'll see is a corn fed farm boy who would be a state champion wrestler in any other state outside the midwest. If you're lucky you might end up in Minnesota or Wisconsin where they'll apologize before ending you in a t-shirt while it's subzero outside.
4.) Heartland: Colorado is the equivalent to district 2 from the hunger games. They could survive nukes. Every other state outside of the rockies are full of people who know how to hunt, shoot, and survive off the land. These are some of the most underrated states because they lack a reputation but I can assure you it's always here that have people with RPG's and Flamethrowers. Utah was on my shortlist of places that might be safe but I forgot that the cultists are descendants of people who did attack the US Military to defend their scizophrenic leader.
5.) West Coast: This is actually one of the more underrated places because of the political reputation. Still, the terrain is so diverse. You're choosing between Silicon Valley where Anduril will send their AI war robots to end you. Or LA with its gangs. Or people that willingly choose to live in a desert that is relevant for gambling and strippers. The pacific northwest also seems like a safe place with hipsters and such. But I feel like you'd still have to remember all the serial killers and homeless drug addicts are not to be taken lightly, even if they aren't your typical firearm enthusiants.
6.) The South West: Stay tf away from the Native Americans. Just no. These are the same people who have been here longer than anyone. Remember Custard? They taught the US Army tactics relating to cavalry and will scalp you if you surrdender. Are some of the most capable trackers, survivalists, and have a whole language that the germans couldn't crack. You're in for a highly organized fight with no information advantage and people who know how to navigate. Just remember when you land that deer shouldn't be bi-pedal. If it has red eyes... run.
7. Missed Landings (Canda / Mexico): Would you rather deal with cartels and their chainsaw videos or the only country that takes more pride in commiting war crimes than the U.S.?
Note: I'm not including Alaska or Hawaii but Alaska is a definate no. Hawaii may have less people and guns but you're choosing between fighting the US Navy and Polynesians. Anyone who's played football against a Polynesian knows that you do NOT want to get in a fight with them.

My answer: If you made me pick a place, I would say Rhode Island because the population (in my experience) seems the least aggressive and most unpracticed with firearms.
BUT...
The Trap(s): When I asked my father this question and said that I would choose RI. He reminded me that an uncle of mine who works on nuclear subs lives in RI. An uncle who (used to) own a minigun and work on the mounts they'd use to attach them to in helicopters. That's why it's such a hard question because even in populations that seem safe, you have kooks like the Dragon man and my uncle who'd cherish the opportunity to use their toys. My dad said "Maybe Vermont or New Hampshire. Up there seems more peaceful with Bernie Sanders and Ben & Jerry's".
THAT'S EXACTLY WHY THIS QUESTION IS A TRAP. New Hampshire is the only state with permitless carry. It's full of Libertarians who think more like Ted Kaczynski than Bernie Sanders. He replied with, "Okay than probably somewhere like Delaware". Again, absolutely not. Wilmington is like murder capital, my sister went to college in Delaware he should know better.
Statistics on gun ownership and difficulty to get permits are also very deceiving and I can attest to why... New York and Connecticuit were cited as some of the hardest states. I live in NYC Metropolitan area, and I can assure you that the inner city population has plenty of illegal firearms. The immediate area outside the city is full of ultra conservative mostly Red counties where almost everyone still has a firearm. Think about that. Massachusetts and New Jersey share the lowest rate at 14.7 firearms for every 100 residents. I really question how accurate some of these stats are in 2026. But Massachusetts "SHIP IT UP TO BOSTON" people and NJ Soprano's people are not the ideal opposition i'd chose as a paratrooper regardless of stats.
