Some people won't understand why Putin invaded Ukraine until it's in a coloring book and even then unless it's a woke coloring book it would be ignored. It's really not hard to understand, but you must first come to grips with the idea that the USA doesn't always do everything fairly and we take actions on others we wouldn't tolerate in return.
Okay, the reason is clear, Russia doesn't want American forces near its borders but at the same time, you can't deny that they want to build a soviet empire again. And the most important part that people ignore is the quality of life. Ukrainians have to either choose the west or Russia. You can't be alone and independent, hope no one believes this bullshit.
Imagine that you live in a poor and corrupt country and Russia/Britain is going to capture your country, whom would you choose? Russian Empire or British Empire? I see America, Australia, New Zealand, UK and then compare them to Russia, Kyrgyzstan, Kazakhstan, Uzbekistan, Georgia, Armenia, Ukraine, etc . Wait, Brits captured those countries but they dramatically improved the quality of life there but Russians? Have a look at post-soviet countries, they are still poor and corrupt, and soviet buildings look awful too. If there is an improvement in these countries right now, that's because of the western world.
Germany managed to build itself very successfully after the WW1 and WW2, the country that was totally destroyed, full of nazis, managed to rebuild like a phoenix, people have a good quality of life there but people in post soviet countries still dive into poverty and they migrate in west to feed their families.
Those blindly stuck in the brainwashed state that Joe Biden isn't running our country off a cliff will never understand. They're too busy in defense mode and brainwashed to believe whatever lies they're told.
Joe Biden is a total failure, can't understand why Americans made such a big mistake. Country, which has a 335 million population and is a leader, wasn't able to put better candidates than Biden and Trump.
