From the write-up that accompanies the video:

This is the second time in a week that former Republican candidates — ridiculed at the time for their foreign policy observations — have been proved right about Russia; Sarah Palin predicted in 2008 that under a weak Obama, Russia would be tempted to invade Ukraine. Incidentally, Palin has been consistently ridiculed for saying “I can see Russia from my house,” which she never said. What a tragedy that, as both Palin and Romney correctly feared, Ukrainians can now see Russians from their homes.
