America is one united federation of states. The federal government still exercises surprisingly little control over individual states, although that control is increasing over time. Most of the federal controls exist merely to regulate inter-state commerce to make sure there are no unfair practices where Michigan can enact laws to keep Indiana businesses from operating in their state. However, two neighboring states can have wildly different laws on local issues. Michigan for the longest time required motorcyclists to wear helmets when the neighboring states didn't, and only allows heavy trucks to have two trailers where other surrounding states allow them to carry three trailers at once.

Classifying America as one solid country all across is, to be honest, quite inappropriate. It's more of a slightly more put-together European Union, with a federal government existing just to make sure everyone plays fairly.

America is not unique in this regard, many other countries have vastly differing state laws too.

I'm not terribly familiar with states in different countries, but I wasn't trying to imply America is necessarily unique. What I was trying to get across is that, for all intents and purposes, each state in the union (read union as union of federated states) is semi-independent and can do almost anything they want outside of printing their own currency. Even that law comes with a stipulation that you can print your own currency but still have to accept US dollars as well.

The parent had asked if the US in particular was one country. In actually, it's not quite that simple. Similar reason why people refer to Canadian provinces by their provincial title in some circumstances. British Columbia is only incidentally related to Nunavut. At the same time, Washington state is only incidentally similar to Alabama.

So compare the US to the EU then. It still doesn't come out favorably for the US.
