Speculation on the consequences of the fall of Putin.
I doubt very much that that alone will break up Russia. Among other things a breakup will cause vast problems in logistics. No part of Russia can stand alone economically.
It is the west that hypothesized the breakup of Russia. We saw it quite recently with the idiotic bombast coming out of some of our leader’s mouths during the Prigozhin “revolution” or whatever that was supposed to be.
