Ukrainian President Volodymyr Zelensky blew up the early professions of unity at the NATO summit Tuesday when he blasted allies for failing to set a firm timeline for his country to join the alliance.

The rattling from outside the tent came hours after NATO announced a breakthrough that would allow it to admit Sweden as its 32nd member, the second new arrival since Russia began its invasion of its neighbor last year.

It came amid a split-screen summit, where leaders declared they were acting in concert, following hard-ball negotiations over NATO's next member and pleas by Ukraine for more fierce military aid amid Russia's bombardment and invasion – while smiling head's of state gripped and grinned at a family photo.
