Most of the World is in support of Ukraine. If I was in Ukraine myself, I would drive a military transport truck back and forth trying to get as many ( willing ) people as possible, to their desired location away from the conflict. And on my way back, pick up people that want to fight to their desired location near the conflict zones. Rinse and repeat.
But this is just an idea, I can't do because I'm halfway across the globe, I don't have some much need skills, and I don't have the resources at hand. I will pray for you.
I DO NOT recommend this course of action though, do to the fact that it puts you in the line of fire.
I'm just saying my mind and this is what I would do if my country was attacked.
Ukraine Is strong and I believe so, because it's people are strong.
Stay safe.
Sincerely - Your friend across the pond.
