I don't think any country today has demonstrated a perfect moral compass on foreign affairs. Nor do I think this lack of a perfectly ethical government is a sufficent excuse for the US's lack of an attempt to demonstrate ethics, nor a sufficent reason to avoid criticising those nations who act unethically.
For example, on this specific issue, the french refusal to accept any UNSC resolution which contained a deadline for war is a specific example of an action that would be considered ethical by Kantian standards.
