America's Back!

Not puzzling at all, really.

He means the part of America America's turning to the world...

Y'know what was a lot better than this? Trump making NATO nations pay their fair share. It was reasonable. It was fair. And it was far, far more respectful of our allies--it treated them like adults. 

Biden's a great representative of certain tendencies of the left--nicey-nice bullshit that fails to honestly assert the reasonable interest of ourselves and fails to treat others as equals. Not equals in the bullshit "equity" sense of equals--say (with respect to nations rather than persons) equal in military might. But, rather: being, in some important sense, equally dignified and deserving of respect.
