The Russia-Ukraine war could get worse.

For one, “A general in charge of Vladimir Putin’s nuclear troops has been killed by a bomb planted inside an electric scooter by Ukraine’s secret services, sources have confirmed. Lieutenant General Igor Kirillov and his assistant were blown up outside his apartment building around four miles from the Kremlin in Moscow,” as reported by Metro.co.uk.

Two, NATO Secretary-General Mark Rutte says Russia is “preparing for long-term confrontation, with Ukraine and with us.” He added that Europeans need to brace themselves for the 

possibility of Russia using “swarms of drones” on the continent,” as noted by Voice of America.

While there’s hope President-Elect could help get this chaos under control, tensions are boiling with the latest killing of Lieutenant General Igor Kirillov and his assistant.
