Ukraine's military chief says 'limited' nuclear war with Russia can't be ruled out

Ukraine's top military officials warned on Wednesday that that a "limited" nuclear war with Russia — which could potentially trigger World War III — can't be ruled out as fighting continues.

Gen. Valeriy Zaluzhnyi, the commander-in-chief of the Armed Forces of Ukraine, and Lt. Gen. Mykhailo Zabrodskyi, who serves as the first deputy chair of the Ukrainian parliament's national security, defense, and intelligence committee, shared their thoughts on the six-month-long conflict in an op-ed published by the country's state news agency Ukrinform. 

The duo wrote that one factor worth considering in Russia's approach to the war is the underlying threat of tactical nuclear weapons usage, arguing that Russia's unprovoked invasion has shown that it "neglects" the concept of global nuclear security, as has been demonstrated by its actions at the Zaporizhzhia nuclear power plant and around Chernobyl.
