The Russians does not have enough missiles to use those strategic long range bombers. They are losing, I wonder why did Russia not mobilized all their people that able to walk to carry arms and walk into the battle to try turn the tide of the battle? Imagine 146 million people walking into Ukraine
Putin can't mobilize the entire population. That's impossible for any country especially in a dictator country like Russia.
1: full mobilization will cause the entire economy to collapse. Skilled workers are needed to run the country. To fix what is broken. To farm for food. And so on.
2: In a dictatorship government it's impossible for full mobilization because you are essentially given weapons to people that really really hate you.
Putin ran out of his supporters. All of his supporters been mobilize. Most of them killed or wounded in Ukraine. What left now are citizens that at best dislike him and at worst want to kill him if they are given the chance. You don't want to give weapons to the people that want to see you dead. Putin and his friends fully aware of this.
So what he got left is trying to recruit foreign fighters in Africa and North Koreans.
This is basically the end of Putin and Russia. Putin will probably be kill by his own people because all his supporters are dead, wounded, and delusions about the war.
It's the end of Russian empire because the core military strength that keeps Russia together is gone. What you got are regional military power that grown in strength and ready to rebel. The hollow out Russian military will only have enough strength to keep the peace in their own stronghold.
