And we all know how fond Obama is of “red lines.”

Via BBC:

Russia’s upper house of parliament has approved President Putin’s request for Russian forces to be used in Ukraine.

He had asked that Russian forces be used “until the normalisation of the political situation in the country”.

Russia’s Black Sea Fleet is based in the Ukrainian region of Crimea, where many ethnic Russians live.

Ukraine’s acting President Olexander Turchynov said he had put the army on full alert but urged people to remain calm.

In a televised address, he asked Ukrainians to bridge divisions in the country and said they must not fall for provocations. […]

The BBC’s Richard Galpin in Moscow says it is potentially significant that Mr Putin’s request was for deployment in Ukraine as a whole, and not specifically for flashpoints such as Crimea.

Earlier, the lower house of parliament had urged the president to take whatever measures were necessary to “stabilise” the situation in Crimea.

During the upper house debate, one legislator accused US President Barack Obama of crossing “a red line” with his comments on Friday that there would be costs if Russia intervened militarily in Ukraine.
