You are of course missing the point. It’s not always about actually carrying through on a threat. Making the threat may still fulfill its purpose. By the way, Trump did sue Univision over a campaign related breach of contract. They recently settled out of court. I wouldn’t bet that Univision came out of it very well.
I bet Univision came out just fine. Really amazing that the new definition of alpha male around here is someone with his lawyers on speed dial.
