It a flag from another country.
It belongs in the cemeteries of that countries soldiers.
Private property displays are up to the owner.
But we don’t fly the colors of foreign countries here in the U.S. I was in Boston this weekend. The Union Jack was not flying on Beacon Hill.
The thi9ng is that there are buried soldier there though correct me if I am wrong.
Nothing wrong with those wanting to remember their history and remember their ancestors.
