I don't support what US did in Iraq or Afganisthan, but you got Russia's motives wrong.
Russia doesn't want to see its neighbours protected from Russia's aggression.
Americans and members of aligned Western nations may not understand this, sheltered as we are within our little comfortable media bubbles that hide the vast, heinous crimes against humanity committed in our names, but from the outside it is very clear that NATO are the aggressors of our age.
You don't get to participate in the massacre of 5% of any sovereign states' population and call yourself angels. You don't get to drop bombs every twenty minutes for twenty years and call yourself a 'peace-maker'.
It is NATO member states that have utterly demolished countless other sovereign nations considered 'inferior' by NATO members' leadership.
How many more million Muslims have to die before this clear bigotry becomes obvious to us in the West? And now the same bigot war criminals have their sights set on Russia.
I think this is pretty obvious, so you have to be somewhat cowardly to not understand this fact. Or, perhaps, extremely privileged to have lived a life, callously unaware of the 34 million refugees from very real, actual wars WE have started since the end of the Cold War ..
Russia is aggressor, not a victim.
I know what I'm talking about, all 4 of my grandparents were lucky to survive 10 years in Siberia after WWII.
There are other racist tyrants currently murdering innocent people across the globe, and you should be able to name them today, instead of relying on the WW2 trope to justify current atrocities.
What WE did to places such as Baghdad and Mosul and Raqqa and Damascus and Tripoli and Yemen in the last 10-20 years - well, those piles of burning rubble are still smouldering. What we are doing TODAY in Yemen, for example, is far more important than what happened to your grandparents.
Russia has nowhere near the amount of innocent blood on its hands that WE, civilian members of the criminal 5-eyes superstate, do. If you want to do something about peace in the world, prosecute the war criminals in your own society. They're still committing crimes, and we - the people - will have to pay for them anyway.
The real target of your ire should be the very real, currently still active war criminals in your own cabinet/parliament/congress.
Prosecute YOUR war criminals before it is too late.
If you feel responsible for war crimes of USA, you should feel personal responsibility for war crimes of Russia too, because you are supporting them. My government hasn't committed any war crimes.
