Gonna write this up in longer form, but folks complaining that the $45bn Ukraine costs are high miss two key points:
1. The direct costs in (US) military aid are surprisingly small; in the order of $19bn this year, and $10.8bn committed (so far) for next year
2. The indirect economic costs of the Russian war to the US economy (i.e. to the private sector not via the government) are in the order of $600-700bn per year. To pick a random company, it's nearly $6-10bn in costs to Apple *alone*.
