A Black American will be treated way better than white Moldovian in most places, at least in countries which are not hostile to the US. American passport is treated seriously by local authorities and such person is less likely to be e.g. detained without cause.
That is most likely true. And it tells a lot about everyday racism in the US that a black US citizen is most likely better treated by police abroad than at home.
But that was a problem during WW2 as well between US forces and their host countries, e.g. the UK or New Zealand where litteral fights were caused by white GIs insisting in racial segregation be implemented by Scotish pub owners and shops. The locals sided with the black GIs.
