Lol, will be quite a bit longer, this might end up becoming a protracted war, but I am doubtful of Russia having enough funds to keep going.
US has authorized about $60bn or so for Ukraine in military funding, so same budget as Russia had for 2021, meanwhile the entire Ukraine budget is for the war and Russia needs to split it for internal police/army, their "research", nuclear arms, etc, so maybe 10-15bn max.
And US made it so companies can direct ship to Ukraine on loan.
Going to be interesting to see what happens in the next two months.
