Frankly do not agree with your assessment especially about Ukraine. Russia still retains maximal aims. Ukraine still retains the ability to militarily defeat Russia but the west has been a day late and a dollar short. Manpower. That is a Ukranian political decision. Ukrainian losses have been not that large compared to their population. Similar in ratio to Russian losses to their population.
Gaza is harder. No good solution. The residents of Gaza choose this by choosing Hamas as their government and starting a war with Israel. Iran is similarly responsible.
Edit: The amount of money the US has put into either conflicts is minimal, had been spend largely in the US, and has no relation to social funding.
