@MLClark I'm concerned that Putin will use this to fire off tactical nukes in Ukraine, trying to look "tough."
It would be the typical strongman playbook. The terror attack, in his mind, make him look weak. So he has to do something that in his mind makes him look strong. Never mind if the true culprits are the target.
The irony is that we warned Russia two weeks ago, very publicly. Our intel was gold. He accused us of plotting against Russia. Oh well, we tried.
