States are NOT an administrative subdivision of the larger country. This is a common misconception. They are not at all like Japanese prefectures, not like Canadian provinces, nor like the counties or parishes that US states are subdivided into.
States are fully sovereign entities that retain to this day certain inalienable rights vis a vis the federal government.
A good analogy is that the US is more like a stronger version of the EU. States like New York and Texas within the US are more like Germany or France-- they've ceder some rights to the federation but retain many others. The US constitution, which is short and easy to read and required reading for the US Citizenship test, clearly outlines which powers are reserved for which part.
>That's not my problem. The states are part of the country.
