“Vatican City has walls around it but allows visitors freely into St Peter’s Square”
They didn’t get far without differentiating the Pope’s wall. “Visitors” being the operative word, people aren’t bum rushing the Vatican walls for a lifetime of free money, education, housing, and medical care while at the same time hating the natural born citizens and claiming racism or some other percieved offense. Their comparison is without merit.
And the USA would continue to allow tourists to visit here, spend their money, and then leave.
