“At the Vatican” where? Not in St. Peter’s or another consecrated space, I trust.
It doesn’t matter. Wherever a Muslim is allowed to conduct a prayer, the area is considered conquered and must be fought for.
In their minds, Muslims now believe even St. Peter’s seat is theirs for the taking.
It’s why it should have been alarming when Bergdahl’s father gave that Islamic prayer at the White House. He, symbolically, gave the entire United States to the Muslims and it’s what they will eventually get around to fighting for.
