At least they have some redeeming value, being free condoms for Aids infested Africa. Yet to this day you've not shown a single solitary good reason why we should be giving free supercomputer software to Iran, North Korea, or any other anti-US government, despite your forceful unending support for it.
Sooooo, Linux is supercomputer grade software? So it is more powerful and capable than the offering from M$?
Okay, if you say so.
Of course supercomputers can run Linux, so do MAC's and playstations, and mobile phones and PDA's... Now I would be more concerned with supercomputer HARDWARE going to Iran rather than the software. The hardware is not free, and I don't believe we're giving them any. Of course even if your fantasy world were true, and Linux didn't exist inside the US, it would still exist outside of it, as does high level encryption software (one of the reasons the US dropped its export controls).
What are ya gonna do, start rounding up the intellectuals in the world so they can't invent or create anything not controled by your master and the USGov?
Not very realistic.
