To me, there's no logical reason for disallowing the merger. If it goes through, American jobs will grow, not shrink. The Japanese aren't going to move mills from Osceola, Arkansas, and Gary, Indiana, to Niigita City.
[Full disclosure: I'm long X.]
The grounds for stopping it are “security reasons” which I understand.
Even if we stop it, we need to address why US Steel Bankrupted to begin with. Unions and hostile business environments. Without that, nothing will change.
upgrade = replace completely.... that which is obsolete and totally uncompetitive
Trump should encourage the success of that merger.
Nippon steel, having invested their capital better than most American steel companies, has a lot of good experience in best practices that they can bring to U.S. Steel.
