I've explained it in my opening post here and elsewhere.
Saudis open their land to Muslims worldwide to come and worship. Regardless of their relationship with their parent countries. Case on poont being Iran.
The Chinese allow Indians to come and worship each year. And the Chinese have fought a war with us and have ongoing border tensions.
The Iranians allow the Parsis to come and worship. And their Mulla regime is on record saying that Zorroastrianism is the biggest threat (to Islam among their populace).
The Iraqis have always allowed Shias to visit their holy places. And Iraq was a Sunni authoritarian regime.
The Sikhs are not even different people.They are of the same soil and same blood. And yet you will dig in the dagger and twist just because a line drawn by a Brit on the map ensured that the final resting place of their Guru fell 3 km in on your side?
Clear enough now I hope.
Cheers, Doc
