No. Don't be silly. Schwarzenegger's excellent speech has ended one phase of Trump's career- which was ending anyway. But Trump was only using the White House as a stepping stone to what he really wanted- a career in professional wrestling.
This is what Arnie is hinting at. He will play Conan the Barbarian taking on Trump- who will be like this bad-ass red-head with a Russian accent decked out in sables and stiletto heels. Nothing else will make America Great Again.
