A Big Financial "Trick"

I've received an email talking about a financial trick that will be done by the U.S government to "save the U.S economy" as the writer said.
The writer explained"
" it has been said that the U.S ministry of financial affairs was buying the iraqi dinar in an average of 150$ million daily,months before declaring "Iraq empty of U.S troops".
the U.S government was buying 1170 iraqi dinar for 1$.
after omitting three zeros from the iraqi currency (which will be done by the iraqi government on the next months) they will exchange 1170$ for 1170 IQ dinar"
