It's an oversimplified view of a very complicated situation, though. And it ignores a) the feelings of the residents in those territories themselves (many would like statehood or the status quo, sovereignty is the least popular option in almost every inhabited territory) and b) the fact that they are all US citizens as well. People always focus on the fact that there is a military base in some of the territories and assume that is the primary reasoning, while ignoring the fact that there are hundreds of US airbases in California alone, along with the marine, naval and army bases. Yet that's hardly the reason California is a part of the US. There's certainly an argument for the territories' status and where they should end up, but I don't believe the primary motivation is militaristic.
