That seems not to be the case. There are many wars in Africa, but not so much money spent. Also, China and countries in Western Europe spend a lot, however, they’re not actively fighting (some missions to some hot spots do not count).
In the Middle East – the boiling point of wars – the biggest spenders are Saudi Arabia, which fights satellite war in Yemen, and Israel which fights against Palestine (as I understand it). But many more casualties come from Iraq, Syria, and Afghanistan, all of which seem to be a mixture of civil wars and satellite wars.
The special case is the USA which will have its separate chart.
This topic is so geopolitical, that I refrain from diving into deeper conclusions, but it’s tempting to say, that more weapons do not make more deaths. More stupidity does.
> Military expenditure in constant USD – some data for USSR and UAE were interpolated using very rough methods – just to fill the gaps and avoid fake jumps. This data have lots of gaps.
> Deaths due to Conflict and Terrorism.
