This should help you understand what's going on:

Take a big step back and look at the trends around the world.

Ask yourself, who will be the 5 permanent members of the UN Security Council when Marine LePen wins the French election?

Putin. Trump. LePen. Xi Jinping. Theresa May.

A new world order is taking shape, with authoritarian and nationalist strongmen at the wheel. Fueled by nativism and populism.

Western, liberal post WW2 democracy is dead.

Welcome to the darkness. And many believe Putin is the one orchestrating this.

The Cold War never ended.

It's also become clear Putin has compromised Donald Trump. To use as either a Manchurian trojan horse (unlikely) or a blunt cudgel to disrupt and de-legitimize our democracy (already happening).

Trump is either a fools puppet or a state-actor. But either way -- he's using the same play book used countless times in history, and recently throughout Europe. And this formula is usually only seen in countries with strange languages or different skin tones. But now it's here.
