Russia threatens retaliation as Ukraine strikes Russian territory with Western missiles

Russia has threatened retaliation after the US and UK allowed Ukraine to use long-range missiles against Russian territory. The Kremlin has updated its nuclear doctrine, indicating a potential nuclear response to NATO-assisted strikes, but experts believe nuclear use remains unlikely. Instead, analysts suggest Russia may increase its hybrid warfare tactics. This includes manipulating migration flows to create political challenges for neighboring countries and conducting sabotage operations. Russia has also been accused of using disinformation campaigns to sow discord in Western societies. Moscow has a history of collaborating with allies and proxies for disruptive operations. Reports indicate that Russia has shared targeting data with groups like the Yemeni Houthi rebels and has intensified ties with criminal gangs in the UK to create chaos.
