While much media attention is being paid to the defiance of the Ukrainian government by various armed groups in that country, you may have missed the story of armed defiance of the US government taking place right here.
A rancher in Nevada named Cliven Bundy had for years been allowing his cattle to graze on federal lands, refusing to pay grazing fees and ignoring court orders to do so because of a crackpot theory that Nevada is a sovereign state and the US government does not exist and thus has no power to levy taxes and fees on people.
When agents of the Bureau of Land Management came to seize some of his cows for this non-payment, they were confronted by hundreds of armed men who had formed some sort of militia to support Bundy and threated to start a shooting war, using women as shields. The BLM agents withdrew and the militia has declared victory over what they consider a tyrannical and illegitimate US government.
The Daily Show had a good summary of the case and how Fox News and the Tea Party Republicans have gone over the edge in their attempts to delegitimize the Obama administration which has extended to supporting what amounts to an armed revolt against enforcing court orders.
