The threats, pressure and ultimatums have come and gone, but Russian President Vladimir Putin has maintained Moscow’s uncompromising demands in Ukraine, raising fears he could use a planned summit with U.

He even envisioned a grand summit to announce a peace deal.But Putin rejected repeated American calls to stop his attacks. And Trump, in recent months, began to take that personally, complaining privately to advisers—and then eventually in public—that Putin would tell him one thing in their phone calls (that he was committed to peace) and then act entirely differently afterward (by bombing Ukraine).

NATO Secretary General Mark Rutte said Friday’s summit between President Donald Trump and Russian President Vladimir Putin in Alaska will be an important test in ending the war in Ukraine.
