And while men with guns very often get shot, they never starve.
Maybe, but we're evaluating the quote "For war, you need three things: money, money and money" which is presumably about money.
I'm from Zimbabwe - everything in Rhodesia was about money. Money needed by the government of the time to stop the guerillas and money needed by the guerillas to house them in neighboring countries, feed and arm them.
Now that Zimbabwe is in terrible economic trouble and has obviously rigged elections and much suppression of opposition voters and of course a military coup that everyone denies was a coup, there is no rebellion and there are no guerillas because they would have no support (no money, no safe harbour, no weapons). The Russians, Chinese, South Africans and DPRK have the situation they want and the US etc don't care about it either.
This seems to imply that money will win you wars, which is not the case. You don't need "money" to get foreign military aid, nor to manufacture small arms in your own factories, especially if you use slaves for that (like the Nazis did).
There are some. An army marches on its stomach. For war, you need three things: money, money and money. Except in a guerilla war maybe. Maybe you're right after all.
