It doesn't provide any real insight into why France is opposed to attacking Iraq. To suppose that it's just to be anti-American, I think, is a little disingenuous. All it really says is that it's using this opportunity to try to hold sway over the EU, and potentially, NATO. It's more possible that they saw this as an opportunity to grab some power, but I don't think that this is the fight they'd want to pick unless they already disagreed with it on some level.
