Why isn’t Cuba and Puerto Rico attached to the US, I thought they were both part of the US (No negative replies)?

Cuba is not part of the US.

However, PR is an island territory, like Hawaii is an island state.  There are plenty of islands that belong to certain countries (like Tasmania, which belongs to Australia) but which are not attached to the mainland BECAUSE they islands.

I hope you are just a rather dull troll and not really this dumb.

Cuba is NOT part of the US. It is a sovereign country. Puerto Rico is a US territory. It’s an island, and nobody can change that. It’s not like we can just move it closer the continental US. It is where it is. There’s plenty of other parts of the US that aren’t attached. Alaska and Hawaii are actual states, and there’s other territories such as Guam and USVI. 

Cuba is an island COUNTRY, a soverign STATE, 90 miles from USA. Puerto Rico is much farther away.

...and Karen, a stupider person down-thumbed you than asked the stupid question.

Asker stipulates the impossible- no negative replies. The question is begging for rejection, hence seriously asking for negative replies.

They aren't attached because that is the way the land was formed. If the US annexes an island, would you expect someone to be able to move that island so it's attached to the mainland US? Cuba is not, never has been, and is never likely to become part of the US.

Cuba hasn't been part of the US for over 100 years.

Puerto Rico is a US territory.  Every time they vote on keeping their status, becoming a state, or becoming independent, there is usually an issue with the election and they just keep the status quo.
