I don't see how that means you can't trust America. A large % does not equal a majority. Look at polling to see where the majority of US sentiment lies.
Similarly, if you look at surveys of Germans, you will see that a large % do not support Military aid of Ukraine, not a majority, but a large percentage. By your logic, does that mean that Ukraine cannot trust Germany?
Due to the fucked nature of the political system in America most people don't matter. Who cares if someone in California supports aid to Ukraine when Trumpistic and Putinistic swing-voters in Georgia does not.
