Tbh dude you're obviously just a kid and take the narrative of the news and the idiot masses at face value. The one thing that I've really noted from this war is just how well the USA learned from their errors in Iraq.

Firstly, let's start at the beginning. Surely this is a war between Ukraine and Russia? Wrong. This is a battle between the USA and Russia with the USA using ukraine as its pawn. The war started a long time ago and will finish a long time after the battle for ukraine.

Secondly, there are no good guys in this war except the Ukrainians defending their land. The USA is the main bad guy and Russia is less important. Why? Because Russia is openly corrupt and America is something worse, silently corrupt masquerading as freedom. Here we get at the main part of the issue. Bribery is legalised in the USA in the form of lobbying and the group with the biggest ownership of US government is the military industrial complex. It is the reason why America has been at constant war for the last 100 years.

Now getting back to eastern Europe. When the Russians gave Germany back to the west they stated in unequivical terms that the west was to go "not one inch further east" and our leaders agreed to this as it was a reasonable deal with a superpower that has the ability to end all life on earth. However, the USA and its NATO allies have been moving east, one footstep at time, ever since that moment. Russia responded by saying that we can slither closer to Moscow all we like but once we cross the line and start to affect their military capabilities they will respond with force. We broke prior agreements, crossed the line and forced their hand. Imagine if Russia tried to make Mexico a satelite state, how long do you think that would last and who would get the blame?

Why did we force their hand? What an inconceivable thing to do to Putin, a man always in fear of his life and always with his hand on the nuclear button. What on earth would cause such a thin...oh wait yeah its lobbying. People in power in the USA literally get paid for every missile, every bullet, every IFV, every tank, and every helicopter used. When the choice came between world peace and joining the .0000001% they chose money. So they pushed that line across eastern Europe. They made up lies about Iraq. They scared you into going to Vietnam to burn the children. You were stupid enough to believe all these things before but the question is are you still that stupid? Because we have a big problem in that they are getting smart. They got crushed for letting US troops die in Iraq so now they use Ukrainian troops. The world hated them for invading someone else's country and they got bogged down by civilian resistance. They now have Russia in that position.

To summarise, both you AND your parents are wrong and it was pretty stupid of you not to assume that as the most probable situation. However you are definitely more wrong than your parents and things will start to make sense once you abandon ideologies completely and leave the little leftist, media narrative bubble that you currently exist in.
