You said a lot of things that lead me to believe you're probably not an expert in international law, so I'm going to exercise my prerogative not to take your word for this.
I'm not an expert. But consider what happened in the rendition case. The penalty imposed on Sweden was
"granting monetary compensation; permitting a new application for asylum in Sweden; and legislative changes prohibiting the use of diplomatic assurances."
Sweden paid less than half a million dollars to each of the two victims. The US would gladly reimburse Sweden 10 times that amount.
