A lot will depend on how this $40 billion is designed to be spent. A lot of money spent in the US on armaments will provide jobs, taxes, and spending in the US. Money for humanitarian supplies may also be spent in the US with the same benefits. Money spent in Europe will enhance the economies over there which can result in an increase in trade with the US. Money spent in Ukraine will no doubt result in a lot of contracts to buy US goods to rebuild that country. Can anyone take a closer look at that bill and do a cost/benefit analysis on who will profit from this investment. Maybe a think tank will do that very thing. At the very least a statement of how much will be spent where will give us a baseline to determine cost/benefits.

***I perceive it is designed to be spent until there is some kind of backlash. That means the Biden folks will reconsider their position once the Ukrainians go past the obambam borders of 2014 towards the borders of 1994.
