There are facts and there are lies.
The fact that innocent people are purposefully being killed in Gaza is just that - a fact.
What you can do is argue that that's okay. What you CAN'T do is argue that that isn't happening.
For example, it is a fact that the US slaughtered hundreds of thousands of innocent people in Hiroshima and Nagasaki.
You can argue it was justified and the lesser of two evil - people do it all the time. What you CAN'T argue is that hundreds of thousands of innocent people werent slaughtered. They were, it just happened.
I'm sorry, you just have to live with that and live with whatever resulting beliefs you may have.
Its important to note that most of those "irrelevant" countries are only irrelevant because they're perpetually under the thumb of world powers. Hence why they petition the UN. And, hence why empires and somewhat-formally colonial nations ignore them.
Ultimately, a lot of the wealth of the West comes from core countries siphoning wealth from the periphery and propping up psueodo governments to place their thumbs on the scale of world politics. Exhibit A: Israel.
