Using a command with ifthenelse for setting a section title

I want to set the title of a section with a command which includes an ifthenelse condition:

documentclass{article}
usepackage{ifthen}

newcommand{region}{Germany}   

newcommand{getValue}{
    ifthenelse{equal{region}{Germany}}{
        Kapitel 1
    }{
        Chapter 1
    }   
}

begin{document}
    section{getValue}
end{document}

This however doesn’t work and I would like to know why it doesn’t work and how to get it working. I receive a lot of errors when I compile the minimal working example which I don’t know how to fix. I could very easily solve the problem in the example by the following:

begin{document}
    
    ifthenelse{equal{region}{Germany}}{
        section{Kapitel 1}
    }{
        section{Chapter 1}
    }   

end{document}

However this workaround is not an option for me in production as I want to use the getValue command in this case more frequently. I had a look at this question however apart from the title the question doesn’t have much in common with this question.

documentclass{article}
usepackage{ifthen,xparse}

newcommand{region}{Germany}

NewDocumentCommand{getValue}{}{%
    ifthenelse{equal{region}{Germany}}{%
        Kapitel 1
    }{%
        Chapter 1
    }%
}

begin{document}
    section{getValue}
end{document}
