I'm reminded of a remark about democracy made by a cynical politician: we'll let the people vote, and decide who's on the ballot. So I voted None of the Above.
I'll borrow from a blogger whose writings I respect and adding some of my own variations. I think they make it easier to categorize various countries than the poll's choices.
Level 3 Friend: Those who will fight beside us.
Level 2 Friend: Those who align with us, but give more passive contributions. (Basing, diplomatic and intel support. Non-combat support. Etc.)
Level 1 Friend: Friendly bystanders. Doesn't try to block our policy and occasionally provides some help.
Neutrals: Sometimes impeding us, sometimes helping.
Level 1 Enemy: Nasty looks in our direction and doing their best to put sand into the diplomatic gears but in practice making little difference. (That one is verbatim. Too good not to keep.)
Level 2 Enemy: Actively working against us but not fighting us.
Level 3 Enemy: A little list. They won't be missed. Probably mentioned in a "why don't you go after THIS country?!" posting about Iraq.
I would also note that those nations that say "we are with you" and then try to grab the wheel and force US foreign policy to match their desires, aren't Level 3 Friends. In addition, threatening to abandon another ally because you think it will stop the US from doing what it's going to do anyway isn't a very good idea either and that other ally might want to wonder if your nation is really an ally. Claiming nations are "lackeys and poodles" because they are working with the US, or claiming they "missed a good opportunity to be quiet" when their leaders say something in support of the US is probably not anything that makes you friend or foe, it just makes you look incredibly petulant.
