Why would you wish for that? Even when AMD was having the upper hand in the performances market (their whole line actually) they couldn't get full market recognition.
Turn this upside down now. Even with Intel dominances in the cpu area, they haven't gain back the fanboy recognition they deserve by AMD crowd. See what I mean?
Why would the EU do this actually? AMD is already in court with Intel concerning exactly this. They have to let it unfold before they can actually do anything concrete or they'll risk having their whole argument destroyed even before it starts. Also, they can probably take 10% of Intel european revenue, they can't touch what hasn't happen on their own teritory. Otherwise, let's all get to Europe and start destroying US, and Canadian, and Russian, and Chinese, and Indian, and any other cointries company that you want a slice of to boost your own economy. See what I mean, IT DOESN'T MAKE ANY SENSES. Especially if that company isn't one that belong to you...
And about the US doing the same? Honestly, I don't think it would be a good idea to beat up one of US dominant technology company and risk having some of that money given to (exemple) Samsung or any other company that isn't in American hands. Don't get me wrong, I'm not even American. But I can imagine what I'd do to preserve technology leadership. It's enough that us (canadian) let AMD get ATI, you shouldn't let the same thing happen. It's this simple.
