I'm not saying some concern for currency stability is absent in decision making but I am not prepared to think it is the dominant criteria for who is or who is not invaded, I'm sure Ron Paul and his devoted band of supporters buy into it, but they see Zionists and Banksters under every bed, so...
But the Islamic world has for some time wanted to see western wealth, especially the US (who supports not only the Zionist regime in Israel but financially and militarily supports many of the "moderate" Middle Eastern regimes in Suadi Arabia, Kuwait, UAE etc), and the desire for the golden dinar has been around a while.
The Economist has this article from 2003 about the OIC.

Since the Islamic world does not speak with one voice, this effort seems relatively doomed in my opinion, even if the desire sees spikes of interest.
