How big of a reason does it have to be for a war to start? How long would it take for one side to win? Would a modern war look much different from the one a century ago? Month ago I, a 25 years old woman, too yоung, too dumb, too happy to know the answers to these questions, would imagine a reason for a war would have to be something way more serious than a fake story created by a madman wanting to take pieces of the earth that don’t belong to him. Yes, blinded by Russian television people believe it, but the rest of the world doesn’t… How can you hide behind few million people you fool while the majority of few billion people know the truth? How can this be possible? How is this a reality in 2022? When you live in a relatively happy country, going through your normal daily routine, working just so you can keep living a life, finding happiness in simple things, you don’t normally think of what would happen if the war started and why would it start in your country if everything seems to be ok and you have a decent president that does their job well. You hear about war and violence in other countries and it’s so far away it doesn’t seem to be real. Yes, you feel sorry for people going through pain but as long as it’s not you it doesn’t feel like reality. More like a book or a movie… you can read or watch and you can get emotional and cry but it’s still just a story, not your reality. 24th of February at 5am I woke up to sounds of heavy explosions from different directions very close to my home… then lots of shooting all day long. I felt fear all over my body, I was constantly shaking, I couldn’t eat or drink.. First thing I did was message my parents and friends.. “do you hear this too?”… Everyone was awake and reactions were different, some were scared, some angry, some hysterical.. No one could eat for few days, no one could believe it happened, no one knew what to do and what will happen next. But everyone knew it’s russia invaded Ukraine. Putler said they were here to protect us from nazism and to stop violence in Ukraine(which is obviously a lie, we were a happy country apart from the parts of us being occupied by him and that’s who was being violent here), said that it’s a “denazification and demilitarization operation” and they will only destroy our military objects and storages. First day it was what they did but next day there were already civil buildings damages and were getting more and more of them each day. They started aiming at civil and education buildings and hospitals on purpose. My city has 60% of schools destroyed, it can’t be an accident. My city Kharkiv gets dozens of rocket hits and dozens of aviation stacks every day. Kyiv is not better, Mariupol is way worse. So many deaths… more civilians have died than our troops… way more. Why?
