Just a few quick questions:

1) Why should the recognition of international judgments be a matter of state law - not merely when the issue is before a state court but even when it is brought before a federal court sitting in diversity (or alienage) jurisdiction. Does this make sense?

2) There is a great deal of variety to the law on recognition of international judgments. For our purposes, just keep in mind the ways in which the law on the recognition of international judgments can differ from what is demanded under the Full Faith and Credit Clause, and the reasons for these differences.
