Invest in Dinars?

While reading the International Herald Tribune the other day, I came across an article about how some individuals are obtaining large amounts of Iraqi Dinars. There are thoughts that once the country gets back into full swing, this now bottomed out currency will gain in value. They will most likely return to Dinars after this conflict because most of the economic infrastructure is still intact. Can anyone list some possible objections as to why it may not be wise to buy Dinars?

Because they are paper? Because confederate money was also paper? Because Argentina's money was also paper? Because the US Dollar is also paper, but they have the largest military, which is really the only way over the long term to maintain the paper illusion? With a gun?

Because the new Iraqi currency might very likely
be different from the old one.

I was not aware that they were considering switching to a different currency. And by the post I made, I was merely taking the logic that since the country is now in despair and the dinar is at an all time low (using the buy low, sell high strategy) it may be useful for one to obtain a small portion in case the country experiences future success and the dinar is their form of currency.
