The Kyrgyz ruling party voted to close the airbases.

It comes down to three things:

• The Kyrgyz wanted a better deal.
• The initial deal mostly gave money to family the now overthrown despot, and the Kyrgyz were honked off by that.
• A Kyrgyz citizen was shot on base by a US soldier, and no meaning action was taken by US authorities against the soldier, inflaming local anger.

This, along with Russia giving them a better offer, was more than enough for them to kick us out of their airbase.
