the overall situation

[ragan]

Can I say this in English?
All in all, however, it became clear that little had changed with regard to the overall situation.

You can but it uses a lot of words to say very little.

"It became clear that little had changed" says the same thing and is less verbose. The chances are that your listener/reader is already aware of what situation you are referring to.

All in all and overall are basically saying the same thing, so removing one would help.
