James Clapper: “His tweet today was about him. Didn't say anything about -- this was a threat to the country and we need to do something…”

I think this reflects Russian insecurity. And it's almost like, Putin needs a rhetorical security blanket, of making threats, like this.

I think the reason they were taken off the list was to provide an inducement or motivation for them to agree to some sort of ceasefire.

I think it has more to do with the psychology of Putin, and Russia. And he needs to assure his own people, Parliamentarians, he was talking to, and for that matter, himself, that Russia is still a great power.

Given the broad distribution, low cost, and accelerated pace of development of this dual-use technology, its deliberate or unintentional misuse might lead to far-reaching economic and national security implications.
