There is no hysteria as far as the US is concerned.

It (the US) is quite calm and only reassuring those who think the US has downslided that the US remains as steadfast in its aim as it was before.

It is merely exerting sending a signal that attempts by any country, no matter who, to dictate unacceptable terms on others, would be to their disadvantage.

If that is, to some, hysteria, then so be it!

And as Carl has replied as to China carrying out exercises with Mexico, I will give it a pass.
