If you could then I doubt anyone would try to stop you
If you stop and think for a minute this is obviously wrong.
We have fishing quotas, ban on testing nuclear weapons, etc.
Yea but Japan still goes into the southern marine whale reserve waters and kills 1000 odd whale every year
North Korea does nuclear tests all the time. If they did it in the middle of international waters, do you think that would result in military action against them? I highly doubt it
I think there would be military action, at least if it was clear they'd done it and there wasn't plausible deniability that it was one of the ones that went missing during the Cold War.
