Donald Trump is bringing about regime change via the election process. He doesn’t need Vlad’s help. Hillary brought about regime change in Libya by murdering Moamar Gadaffi. It’s what she knows to do. Was Vlad mad at the uranium deal that Bill and Hillary piped through their international RICO organization? Did Barry not give enough flexibility to Putin after the election, thus Putin takes it out on Hillary via Assange and, by a convoluted extension, Trump? The FBI will get to the bottom of all of this....trust them. Yeah right!
In my view it is a serious error to assume Mad Vlad wants to conquer the world. He knows he lacks the where with all.
It is possible, perhaps even likely that Vlad knows Hillary would be a world disaster and getting rid of her is beneficial in the long run.
Oh and one more thing...... there is revenge. Bubba pardoned the exiled Marc Rich who effectively stole and sold the USSR aluminum stock pile.
