OBAMA: Ukraine Invasion Will Be 'A Costly Proposition For Russia'

President Barack Obama said Monday that Russia is "on the wrong side of history" and in violation of international law for sending troops into the Ukranian region of Crimea. He also promised America will make Russia face consequences for its actions.

Before a bilateral meeting with Israeli Prime Minister Benjamin Netanyahu at the White House, Obama told reporters the United States is considering economic and diplomatic options to "isolate" Russia and the government of President Vladimir Putin.

"There are two paths Russia can take," Obama said.

Obama noted the "world is largely united" in thinking Russia is in violation of international law. At home, Obama said Congress should immediately consider an aid package to Ukraine.

"Over time, this will be a costly proposition for Russia," Obama said.
