US, South Korean, and Australian navies join forces to intercept shipments of nuclear materials...

I venture to say this may not favor allies, since it may be deemed provocative. Allies cannot stop, board, search or seize from ships on the high seas. There is international law on Search and Seizure on the High Seas, I believe.

Locking the barn door after the horse is gone. Hope our intel is good, if we intercept ships from other countries are stopped and searched. This will definitely be seen as provocative by many.
