Rhetorical situations

In English 503, you have spent a lot of time dealing with rhetorical situations on a local level because most of your discussions have led to the application of rhetorical theory in your workplace contexts. However, contemporary theorists are also considering the role of rhetoric in a global context, which is changing quickly. For example: Barry Thatcher (2010) argues that rhetorical approaches are often based on theories about local contexts, and these approaches must be redefined or adapted to address rhetorical problems beyond the local. To what extent do you see a theory you have used as suitable for addressing global rhetorical problems, such as communication across cultural boundaries?
