I see kt is still of questionable character.

Trying to inject a little bit of reality, Putin fancies himself the restorer of Stalin's Soviet Empire. That's why Putin went to war in Georgia, when he knew final-year-lame-duck GWB was not in a position to do much to oppose him. That's why Putin went to war to hack the Crimea off from Ukraine, when he knew Obama was too weak and decisive to do much to oppose him. Continuing that pattern, Putin knows
LIEden is a marginally aware, indecisive weakling. So Putin acted accordingly, trying to hack off another piece of Ukraine, or simply annex it.
