The Red Cross considers 1500 the floor for the US: https://emergency.lacity.gov/sites/g/files/wph1791/files/202...
not that much to the minimal amount of 1400 the CNN article found occurring. Horrible I agree, but not that far off from the Red Cross floor for aid distribution with the USA.
The UN provides much less calories (currently 552 to refugees from Sudan's war) yet says it can provide more than Israel in aid Gaza. Is the UN anti Sudanese/Kenyans because it claims to have food for 2 million on hand yet won't feed the starving 800,000 in Kenya? If it has food for Gaza's 2 million that is isn't giving out, how can it justify not giving at least part of that to the smaller 800,000 war refugees in Kenya? The UN itself says it's a crime not to give out food in those higher quantities if there are stocks of it. The UN has stocks. The UN does not give those stocks out to those in need, only giving 552 calories.
Kenya has the ability to grow food. Gaza doesn't. Israel has destroyed 100% of the farmland and shoots anyone who walks around freely outside of a tiny fraction of the Gaza Strip.
For 1 we should be looking at results and the situation on the ground, not the guidelines for what's "the proper way to do things". Were people in Germany starving or not, are people in Gaza starving or not? If the answer to either is yes, then it is / was a problem.
Secondly, what we consider ok changes over time. Go back far enough and killing prisoners, taking civilians as slaves etc were all considered ok. We frown on those now.
