Here’s the latest statement from the White House on the tense situation in Ukraine and Crimea: President Barack Obama Says Putin Is on ‘Wrong Side of History’.

President Barack Obama said Monday that if Russia continues an incursion into the Ukrainian peninsula of Crimea, the United States would take diplomatic and economic steps to “isolate” the country.

Speaking to reporters in a meeting with Israeli Prime Minister Benjamin Netanyahu, Obama said that invading the Ukrainian territory was a “violation of international law” that puts Russian President Vladimir Putin “on the wrong side of history.”

“What cannot be done is for Russia with impunity to put its soldiers on the ground and violate basic principles that are recognized around the world,” Obama said. Qualifying his threat on Friday that “there will be costs” for a Russian invasion, Obama added, “Over time this will be a costly proposition for Russia.”

The State Department also made a statement today that economic sanctions against Russia are “likely.”
