Why should you feel more shame than anyone else?
My country recently separated mothers from their children near Mexico, provides bombs to KSA to kill in Yemen, abandoned Afghani friends (especially the women), doesn't help matters in Syria. We had a President who literally got Capital Police and others killed in broad daylight! What could I do about it? I never got a chance to vote for Bernie Sanders, or any anti-war candidate. Sure, I think my government is better than Russia's government, but the people? And we have homeless, opioids, increasing wealth gaps, etc., etc.
It isn't about what-about-ism. We can only act as virtuous as we can individually. NO RUSSIAN had to pick up arms and go into Ukraine. (Zoltin on YT will never get past this) They could have all stayed home. But of course, it's complicated, complicated in a way you or I will never fix.
If you had tried to help as many people convert money early on for dollars most wouldn't have listened and someone probably would have reported you and you'd be stuck there today. And what would you have really accomplished, even if you succeeded? It's just money. Money isn't the problem. There's a lot of money in Russia that wants Putin gone. But what can it do against a personal 400,000 person army?
We just have to hope the Putin regime falls sooner rather than later.
