Can you buy dinar in the US?

I'm curious, is it possible to purchase dinar, the official currency of Iraq, in the United States? I've heard of people investing in foreign currencies as a potential way to diversify their portfolios, and I'm wondering if dinar is an option that's available to those in the US. Could you provide some insight into the process of acquiring dinar, if it's indeed a viable option? Additionally, are there any potential risks or considerations that I should be aware of before making such an investment?
