Yes, you can fly other country's flags with the U.S. on an in-ground flagpole as long as it as the same size or smaller than the U.S. and the U.S. flag is flying above it.
Why do people teach the u s. Flag is the American flag and that is not true. First America is a continent and has no flag just like Africa Asia has not flag. Nations on these continents have flags the star and spangle banner is the united States flag not America. America and the united states are two totally different things.
@@matthew-irl truth needs to be told and saying the u.s. fish is the American flag is a out right lie to it's highest degree. The u.s banner is a banner of commerce it's a business flag as the united States is a business,not a country.
