Depends where. It has allies and has enemies and frenemies. Since Trumps first term, it’s viewed as more unstable and unreliable. I don’t think his second term will alter that view. America was a lone superpower after the fall of ussr. So, it provided stability. Now with the rise of China, and a more unified EU, it’s less powerful, but still the most powerful. The USA has done some terrible atrocities and continues to support many. The most recent being the current genocide in Gaza. Do you think Palestinians view the USA as a bad actor?
Some would still come, but much less. I personally have chosen to avoid travel in USA during trump 1. I would again if things get crazy. I know that Australia, for instance, lists USA as risky for gun violence and demonstrations. It particularly calls out election and inauguration as to be avoided. It’s still noted as safe, but not as safe as Australia due to general violent crime. https://www.smartraveller.gov.au/destinations/americas/united-states-america
