What can we do to help Ukraine?

Besides giving money or shelter (to the refugees) what else can we, as individuals, do to move the needle in favor of Ukraine. 

One tough question indeed. 

Has any one a unique, strategic idea to share that could lessen or stop the effect of the Russian invasion? 

There must be tactics, moves or other stratagems that could either save that country or alleviate its current suffering.

What are your thoughts or suggestions on the matter? Please share them here if you have some. In turn, 

I’ll let you know what I have done...
