Steve Bannon says the biggest of the converging crises is the massive amount of global debt, $300 trillion.
"That will converge in a couple of years and lead to a massive financial crisis that will dwarf 2008 and what happened in 1929," Bannon said.
"Right now we don't have a political class who can deal with that." Bannon also warned of the beginnings of a kinetic third World War on the Eurasian landmass that has many of the attributes of even the Second World War.
"Underlying all that is a mass invasion of Europe and the United States," Bannon added.
"Governments will fall because of that.
The populist and nationalist movement will be a solution."
