So, whose flag are they flying at the protests?

Judge for yourself.

The Son of the Shah campaigns for his return to the throne!

The flag of the Shah in front of the White House

The flag of the Shah in Toronto

The flag of the Shah in Irvine

The flag of the Shah at CNN

The flag of the Shah in Salt Lake City

The flag of the Shah at Bellevue Washington!

Remember, this design flag has not been used for 30 years. They are not just lying around "Flags-R-us". Somebody ordered these flags to be made up in advance of the protests!

To put this in context, imagine there are a bunch of Germans urging the overthrow of the present government of Germany, and they wave the Swastika, the flag of Hitler. Would you not be concerned?
