Just to make sure I answer your first question, if you didn't distill the answer from my response...

No, it is not symbiotic.

It is parasitic, and as soon as the host dies, the parasites will jump ship...probably to the next host, be it Iran, Syria, or whoever... unless, of course, we Americans take our country back from those who are selling it and its dignity and integrity off to the highest bidder...or highest contributor.

Fish on...

P.S. If you think it is "symbiotic", I'd love to hear your reasoning...
