President Barack Obama asked Russian President Vladimir Putin on Saturday afternoon to return his troops to their barracks and to remove his forces from Ukraine.
However, Obama didn’t threaten or promise significant retaliation if Putin continued his advance into the majority-Russian parts of the Ukraine, according to a White House statement about their 90-minute phone call.
“If Russia has concerns about the treatment of ethnic Russian and minority populations in Ukraine, the appropriate way to address them is peacefully through direct engagement with the government of Ukraine and through the dispatch of international observers under the auspices of the United Nations,” Obama told Putin, according to the White House statement.
