> then I don’t want to hear a peep about us taking any other actions in the world that we deem just
I think the noteworthy peeps are not about the mere fact that we involve ourselves in the world outside our borders but that we often do it pretty badly. We attack Iraq with "shock and awe" over WMDs that do not exist, and create the Abu Ghraib prison. We drone strike weddings. We set up puppet governments ... for a while. We sign up for climate accords and then back out (multiple times).
I read his point as, "if we have an obligation to fix other people's problems, we shouldn't be subject to complaints when our foreign adventures go wrong".
And I think that's crap; we have both an obligation to try to fix the important problems that wealth or force can fix, and we have an obligation to use both carefully and ethically.
> which I would rephrase as "We can't be police and not police at the same time.
To be clear, in this turmeric story, they did an ad/leaflet campaign about the issue, and then Bangladesh's own Food Safety Authority cracked down. This wasn't about the US enforcing its laws or standards anywhere else. Getting involved and helping to solve a problem doesn't need to mean being the police. And I'm not an expert, but I think almost none of the stuff that flowed through USAID was about being "police".
