So what do you see as the CTBT's significance in today's changing security environment? And specifically, noting that it's not yet entered into force, what is its relevance?

The CTBT, as you say, is turning 30 right this month, 30 years since the treaty text was available and open for signature.

And in that 30 years, it's amazing what has been done.

One thing is that we have near universal support for the treaty.

We have 188 out of a possible 196 countries that have signed the treaty, committed to its object and purpose.

And of the other eight that haven't yet signed, almost all of them actually agree with the object and purpose.

So almost universal support, which is fantastic.

So thinking a bit more then about the mechanisms that are in place under the CTBT, are there any examples from the past where misinformation or disinformation has arisen from an event or a misunderstood event?
