Does anyone have sources for this?
I'm not an expert, and a quick look on Wikipedia shows that comparing just 2 recent big wars, the USA coalition's invasion of Iraq (2003-2011) killed approximately 151k to 655k[i] Iraqis, while the major Russian invasion or Ukraine (2022-ongoing) killed about 200k[u] Ukrainians.
Anyone have better numbers, and other non-defensive invasions?
