Charles Krauthammer told viewers Friday on "Special Report with Bret Baier" that President Obama's statement on the latest Ukraine developments showed "weakness," and implied that "we're not really going to do anything" about the political upheaval in Ukraine.

On Friday, armed men, allegedly Russian military forces, entered the Crimea region and took control of two airports. President Obama then delivered a message from the White House briefing room, saying he was "deeply concerned" by the reports and that "there will be costs" for any military intervention in Ukraine, though he declined to specify what those costs might be.

Krauthammer, however, said the president's statement failed to make strong waves.

"The Ukrainians, and I think everybody, is shocked by the weakness of Obama's statement," he said. "What he's saying is, we're not really going to do anything."

Krauthammer, a syndicated columnist and a Fox News contributor, said Russia will interpret Obama's remarks as complacency.

"He said, any violation of Ukrainian territory is destabilizing, and that's not in Russia's interest. He is instructing Putin on what's in Russia's interest?" Krauthammer said.  "I can assure you, Putin has calculated his calculated his own interests, and he's calculated that detaching Crimea from Ukraine and making it, essentially, a colony of Russia, is in Russia's interest - because he knows he has nothing to fear from the west, because it's not led by anybody. It used to be led by the United States."
