Vladimir Putin commands the world's biggest nuclear arsenal and stakes his authoritarian grip on providing strength and security.

So the massive terrorist gun attack at a Moscow concert hall on Friday killing more than 130 people is the Kremlin's worst nightmare.

ISIS-Ks claimed responsibility. Russia, without any evidence, says Ukraine played a part in the attack.

Two of the four suspects pretty guilty after they were allegedly tortured by Russian security

services. One reportedly received electric shocks to his denitals. Another was allegedly forced

to eat his own ear. Well, attention is now turning to how Putin will respond. Does this attack on Russia make the world an even more dangerous place?

To discuss this and more, joined by Annie Jacobson,

investigative journalist and author of the new book, A Nuclear War, A Scenario.

Well, it's a scenario, Annie Jacobson,

that we're all beginning to have to get our heads round, isn't it?

Because the saber rattling from Putin

before this about using nuclear weapons was getting louder and louder. I can't imagine it

will get any less loud following a terror attack of this magnitude. First of all, welcome to

Uncensored. Let me just say that from us top. Great to have you.

Thank you. What's your take on this terror attack? We hadn't heard much from ISIS for quite a while.

Why have they targeted Russia? How damaging is this to Putin?

I mean, it is an interesting concept we're dealing with right now. And when I think of Putin, I think of the fact that he is the longest serving Russian

president since Joseph Stalin.

And so everything that happens in his orbit is about power.

I mean, to come out of the gate and blame, you know, your sort of obvious adversary Ukraine

for something that the rest of the world clearly thinks is ISIS puts him at odds with a lot of

people.
