The Grand Mufti of Saudi Arabia and the President of Indonesia are uncomfortable with their heritage as presented on videos of beheadings and child-rapes live on the world’s computer monitors.
In the unlikely event that they were serious about their discomfort, what would it take to defund the Islamic State?
It controls oil production facilities capable of supplying it with the equivalent of $3 million daily.
That is a hard asset, easiest to deprive them of.
The softer asset of the bank notes they stole might be more difficult to deprive them of.
What currencies did they steal?
If they were specie of major international currencies, it could be difficult.
If they were currencies of a smaller country, might it be simply a matter of devaluing or invalidating the stolen currencies?
