Donald Trump and Vladimir Putin might be chasing different outcomes from the much anticipated Alaska summit on Friday. While the US president believes he can make a ceasefire deal with Putin, Russia's leader might have other ideas.

"Trump wants to exhaust all options to have a peaceful end to war," the White House said Thursday. Whether those "options" are good or bad for Ukraine is key.

The one-on-one format sought by the Kremlin maximizes the advantage of Putin’s experience and sets the stage for a well-worn playbook of half measures to drag out negotiations.
