The news on the massacre in Uzbekistan is sketchy, but it seems clear that troops fired on a protest meeting, killing dozens.
The massacre followed violent protests in which government buildings were taken over, and prisoners, including alleged members of Islamist groups, were set free, but it appears that the protestors were simply listening to speeches when the troops attacked them .
The US currently has an air base and around 1000 troops in Uzbekistan. They can’t be regarded as neutral, and their presence clearly supports the mass murdering and torturing dictator Karimov, someone who appears indistinguishable from Saddam circa 1980. A literal reading of Administration rhetoric would suggest that the US should use its power to overthrow Karimov , but there’s zero possibility that this will happen (the official US response is an appeal for restraint, directed mainly at the protestors). But the troops should be withdrawn immediately, and all ties with this evil regime broken.
