Given the keystream output from RC4 (ARC4), is there an inverse RC4 function which would give me either the key schedule or even the original key.

I have the plaintext, the cyphertext, the key stream, and the nonce which is mixed with an unknown key. I'm trying to recover that unknown key part.

Assume that the first N-bytes of the keystream were not discarded.

If you're an American reading this, and you've never been to Europe. What are some of the bad things/stereotypes you hear about it? I've heard some Americans go on and on about how Europe is such a horrible place, and how to USA is superior in all ways and crap like that. But I can't remember any specifics right now; So someone tell me something specifically bad about Europe. Like, hypothetically, if I was going to move to somewhere in Western Europe for the next several years, how would you talk me out of it?

[So far, my experience here is that everything really is better in Europe than in the US.]
