The United States is not a bubble. Outbreaks overseas can have impacts here not only through possible infection reaching here but also the potential for the disease to develop antibiotic resistance in an improperly handled antibiotic treatment (such has cutting off access to the drug mid treatment) and of course 2nd order effects like outbreaks disrupting global supply chains.

The COVID 19 global pandemic was only a few years ago and its impacts lasted years. TB is not as infectious and would have a reduced spread but treating it helps contain possible issues and may one day lead to its eradication.

How does cutting funding reduce risk? Reduce suffering?
