The month-long invasion of Ukraine has damaged the country severely. Putin relentlessly orders attacks. There have been thousands of deaths for both sides. There is only one way for Putin’s reign to collapse: internal uprising.
This is when people from the inside of the country itself are against the President. When these people are in large numbers, say a quarter of the Russian’s 144 million people, there is nothing you can do but give up. Autocracy is when one person is made to decide all the decisions, and is extremely biased. But, when you have the people who decide, basically democracy, the decisions are usually made unbiased and normal. The sanctions against Russia have only been set to diminish this prejudiced rule.
