I’m sorry, but if I’m giving someone who is - at best - an acquaintance of mine $50 a month out of the goodness of my heart and then one day decide to stop, that’s not a broken promise. If that acquaintance got angry at me about stopping I’d get pretty upset back.
I really don’t understand what link you think there is between USAID spending being cut and inflation. Gas prices are obviously Iran. Everything else started years ago.
