President Obama said Wednesday that the U.S. would not take military action in Ukraine against Russia.

“We are not going to be getting into a military excursion in Ukraine,” Obama said in an interview Wednesday with KNSD, the NBC affiliate in San Diego.

“I think even the Ukrainians would acknowledge, for us to engage Russia militarily would not be appropriate and would not be good for Ukraine, either,” Obama added.

Russian President Vladimir Putin this week signed a treaty that annexed Crimea as part of Russia, a move that was condemned by the United States and the West.

Obama dismissed the notion that Putin was acting “out of strength,” telling the San Diego station the annexation of Crimea was an action taken “out of weakness.”
