Incorporation of foreign and international rules and principles will require skills of synthesis and distinguishing that are distinct from traditional domestic
legal reasoning, and they may require appreciation of important differences
in foreign / international
legal, political, or perhaps even cultural
context.63 International
legal rules often play a complex role
in domestic law, presenting issues of interpretation and enforceability that do not easily fit within traditional domestic United States legislative, administrative, and judicial
legal structures.64 Integration or application of rules from foreign nations may be even more complex, especially where those systems are substantially different from our own.65
Additionally, there may be discrepancies between the form and function of foreign or international law that affect their proper application.
Additionally, the US continues to insist on its controversial
legal position to justify self - defense, including
in the
context of nuclear weapons,
in response to efforts by non-state actors.
