I do not believe the trade war will necessarily expand our employment base. I don't see how getting IP reform will significantly affect middle America. It will still make sense for American entrepreneurs to use Chinese labor. They'll just make more doing so. I also don't think there is any convincing line of reasoning that this trade war was the only way to achieve IP reforms.
However, I don't see significant harm in trying. Our country does not need additional stock gains at the moment, and inflation has not been a problem. Good for Trump for possibly sacrificing some "headline" numbers for long term economic improvement.
