A man who once taught Vladimir Putin body language tricks to help him be respected on the world stage, says the Russian leader's "diseased brain" now threatens to destroy the world.
Body language expert Allan Pease met Putin more than 30 years ago when he and his wife spotted a gap in the market after the fall of the Soviet Union.
The Australian met the then-39-year-old in 1991 in his home city of St Petersburg, having originally gone over to Russia to met President Boris Yeltsin.
