Blowback

Brad Barrett hasn't specifically discussed the concept of "blowback" in the context of international relations or US foreign policy in the retrieved clips. Instead, in one episode, Brad and his co-host Jonathan Mendosa mention receiving some "blowback" from dentists in response to a recent episode about optimizing healthcare expenses, stressing that it wasn't aimed at discouraging use of local dental services 1.

For more context-specific discussions on international relations, you might need to refer to other sources or experts who focus on that field.
