Several folks here are still completely missing the point of nations respecting each other, and what a lack of such respect leads to.
And it's not JUST a matter of the United States, and I never said it was. It's a matter of a NUMBER of nations joining together, and telling the Iranians that they don't have the right to decide the course of their own country's future.
That has nothing at all to do with whether or not any of us approves of anything another independent nation does or doesn't do.
Again, this form of international RESPECT has nothing at all to do with APPROVAL. I say again, since more than one person keeps missing this: respecting another nation has nothing to do with approving of them.
Again, this is a mechanical thing. A direct result of refusing to RESPECT that other nations can decide how to conduct their own internal affairs without consulting the world at large, and worse, actively working to prevent them from living as they wish to in their own lands, always tends to have the natural result that said people will become angry, and will resist or even attack in return.
This mess wasn't created recently. It goes back a very long ways. Each side is reacting again and again to the other, and restarting the hostilities over and over again. Repeating the anger and reciting the past grievances accomplishes nothing but renewal of the hostilities. Each side's arrogance is cited as proof that the other is entirely justified in anything at all that they do in turn.
Why is it OK for Iran to dabble with Nuclear Power,while the rest of the World is crapping their Pants at the very thought of using Fission in new-Generation Nuclear Reactors,which are immune to Thermal Runaway?
