Americans get a lot of unnecessary derision because they insist on calling football ‘soccer’ etc so I wouldn’t want to exclude Americans. But it has to be on merit otherwise what’s the point?
The point of my post is that arbitrarily limiting a position to those with a specific nationality, necessarily limits the quality of those in said position. So if an American is good enough sure, but if they’re not going to improve it then not a chance.
All fair comments. Though when a culture needs fixing, importing new people and their ideas can be a helpful start.
