Russia has ‘nuts’ too.
Putin has many conventional weapon programs underway. He will rely on those.
Putin will try to kill lots of Ukrainian soldiers while trying to minimize Russian losses.
Putin has been truly efficient when it comes to minimize russian losses. Only +200.000 Russian soldiers killed and/or injured for life (so far) - after only one and a half years of war...
In recent history, Russia lost 10.000 soldiers in Afghanistan after 10 years of war...
Putin still has some Russians in combat age left to recruit though.
One problem: 1,5 million young and smart anti-neo-Soviet Russians fled Russia right in the beginning of the war...
So Putin will have to rely on Wagner or similar once again...
