A climactic tweet from Артем Клюшин

I am referring to the one at the top - what does this mean? What important call was/is being/will be made? Is this possibly about cutting aid to Ukraine, or about something even worse?

Also, the Latin (tweet 2) means 'They thought that everything was decided yesterday, but everything will be decided today'.

I previously expressed doubts about whether he was genuine; does anyone have any further insights?
