The following article fron CNBC states:
Trump says US stands with Saudi Arabia despite journalist Khashoggi's killing.
McGraw-Hill Dictionary of American Idioms and Phrasal Verbs defines the phrasal verb stand with someone as:
to unite with someone, as in defense.
- Don't worry. I'll stand with you to the end. He stood with her and they faced the threat together.
I could not find the definition of stand with on other online dictionaries, but the usage made by the CNBC appear to convey a different meaning from the one in the dictionary.
Are there other definitions and usages of “stand with?”
Is the expression used also in BrE?
