on history: After Chmelnitskiy, imach shmo, rebelled against the Poles, his people decided to become an autonomous part of Moscow’s Russia, and Russia agreed to defend them against the Poles.
I recall that Chm-ky wanted to partner with Russkiies against Poles, but they know only one part of partnership – of a master and an eved knaani, so he got what he earned. Midah k’neged midah indeed.
