President Obama on Wednesday used a speech in Estonia to deliver a stern warning to Vladimir Putin's Russia, saying the NATO alliance would not accept Russian annexation of "any part of Ukraine" and that "borders cannot be redrawn at the barrel of a gun."
The president's stop in the small Baltic nation en route to a NATO summit in Wales was designed to send a message to Putin, and he devoted the bulk of his 30-minute address to condemning Russia's aggression in Ukraine and vowing a unified response.
"We will stand firm and united to meet the test of this moment," Obama said.
The speech at the Nordea Art Concert Hall came hours after Ukraine retracted a statement claiming its president had struck a ceasefire agreement with Putin.
Obama called Russia's armed support for the separatists in eastern Ukraine a "brazen assault" on the nation's territorial integrity.
"We will not accept Russia’s occupation and illegal annexation of Crimea—or any part of Ukraine," Obama said.
He also used the speech to reassure Estonia and other Baltic nations that NATO would defend their sovereignty just as it would the larger, more powerful members of the alliance.
