Being completely passive and cold and ignoring the suffering of those around you is still better than actively inflicting suffering.

Because our countries aren’t sovereign. Capitalism is a system where capitalists dictate politics. But capitalists aren’t loyal to their home countries, they’re loyal to their the capitalist class. So they have no incentive to dictate politics in the benefit of the countries they rule. The USA as an institution is their main instrument and army. So of course they’ll protect the USA.

If you doubt me, you can try to verify it. Pick a small handful of capitalists in a EU country, and check where their money is. If they own more stocks in USA companies than they do EU companies, then assuredly they’ll prioritise the USA’s economy over the EUs economies.
