Russian President Vladimir Putin’s eschatological talk of nuclear Armageddon at this year’s Valdai forum has stirred up heated debates on how well his description of Russia’s potential use of nuclear weapons matches the country’s official military doctrine. However, a close look at Putin’s Oct. 18 remarks and Russia’s 2014 military doctrine reveals that, while Putin deviated from the language in the doctrine, he did not lie on the first use issue. Nor did he seem to be hinting at a shift in Russia’s nuclear posture. More likely, he was signaling to Washington that the existing nuclear arms control treaties need to remain in place for the sake of ensuring strategic stability in the U.S.-Russian nuclear dyad and avoiding an accidental war between the two countries.

This month marks the tenth anniversary of Vladimir Putin’s first military intervention abroad, in Georgia. Since then there have been two more, continuing to this day, in Ukraine and Syria in 2014 and 2015, respectively. And still it’s worth asking: When does Putin authorize the use of military force, overtly or covertly, against other countries and why?
