Trump’s biggest move, misreported (Ad)

The media and financial pundits are all misreading Trump’s actions. They think Trump wants to make Canada the 51st state because he’s desperate for critical minerals… They think his involvement in Ukraine is just another resource grab… They think his tariffs will wreck the economy… But they’re all missing the bigger picture.

This is fast becoming the world’s most sought-after resource.
