Putin is now positioning troops in Belarus where they could be roughly 100 miles north of Kyiv, with the possibility of seizing the capital and deposing the current government. It is hard to imagine that this would happen smoothly or that ordinary Russians would turn a blind eye to the ensuing carnage. It is one thing to unleash the military on Ukrainian forces near the Donbas, but attacks on major cities like Kyiv and Odessa would leave a completely different impression of the cost of war. Ukraine is not going to go quietly, and there are bound to be lots of Russian casualties, not to mention innocent civilians. It appears that Lukashenko would have little choice but to allow Putin to launch a fresh invasion from Belarus territory, now that his brutal regime depends on Moscow for its continued existence. The excuse for positioning those troops at a time of high tension is that they are there for joint exercises with the Belarus military, although it isn't clear that Putin even consulted with Lukashenko before shifting troops into that location.
