WASHINGTON (AP) — Russia’s decision to send paratroopers into Kazakhstan, where a crackdown on violent anti-government protests has left dozens dead, injects additional uncertainty into upcoming talks over a possible Russian invasion of Ukraine. The question is whether the unrest in Kazakhstan has changed the calculations of Russian President Vladimir Putin as he weighs his options in Ukraine. Some say Putin may not want to engage in two conflicts at the same time, while others say Russia has the military capacity to do both and he will decide separately on whether to attack Ukraine. The instability in Kazakhstan may even add new urgency to Putin’s desire to shore up Russia’s power in the region.
