I respect your concern.
Putin decided to do what he has done because he can.
My thoughts are how sad it is for Ukraine to be in the situation they find themselves in.
I think the Ukraine gov thought the US and Europe would do more to help in the conflict than they have.
Instead there's a worse world refugees crisis, increased hunger and famine in poor countries.
Also nobody knows when or how the war will end or what the world future will be.
