And they knew what to do with a bad ruler.

Pennsylvanians cry when they read this.

To be fair the places with good roads generally don't experience checks notes Winter. Or didn't until climate fuckery.

Both of your reasons are wrong.

Now, excuse me, I'm lobbying Congress to move to LA.

Move it to Seattle!

Constantine created Constantinople/Byzantium as a second capital. At that point, there was an Eastern and a Western Roman Empire. When people talk about the fall/decline of the Roman Empire, they usually mean West Rome. East Rome is more often called the Byzantine Empire.

The Byzantine Empire declined over the centuries, but Byzantium remained unconquered for 1000 years after the official "fall" of the western empire. In the 15th century, it was taken by the Ottoman Empire and is now, as Istanbul, the capital of Turkey.

Constantine adopted Christianity as the official religion of the empire.

That kept the empire alive for a couple more centuries and gave the Byzantines another millennia of time to fuck around. Christianity was central to Constantine's continued control of the military, which had stopped being an elite profession of the nobility and transitioned into a proletarian wage labor position.

Absent a strong socially cohesive force to keep his armed forces loyal, the Roman state would have disintegrated a lot sooner.

Not sure if bait or not

Say... Florida? In the Mar-A-Lago vicinity?

Rome fell for a lot more than two reasons and it took at least 200 centuries during which they suffered civil war after civil war between emperors fighting for power, severely weakening the empire over this long time.

So while the US currently might have a few facets similar to Rome during it's decline, it differs in a lot of other points. So I'd say it's simply not comparable.

That's an opinion, not a fact. Here's another opinion.

Constantine adopted Christianity because the people adopted Christianity and if he didn't follow suit, bad shit would've happened, mostly to him.
And the capital was moved to Constantinople to account for the growing asian influence that was beginning to threaten the empire. The west fucking up after that would have happened regardless of the capital being there.

The Abbasids fucked up the same way and no one gives them shit about it.

Does it count if it's only 250 years?

We have another 200 years or so as a republic, this is our... [checks notes] Second Punic War.

Rome's "good roads" would be shit by todays standards. They didn't have to deal with thousands of heavy cars and trucks driving over them daily.

America's roads are shit because maintaining roads is expensive and suburban sprawl means you need to maintain a hell of a lot of road mileage per capita.

Fuck car dependency.
