1. a way to make money (and a lot of it) 2. a way to maintain control, blame someone else for your shortcomings/problems (sadly the russian-ukranian war is for this very reason) 3. to a lesser extent, war is a way to curb population/weed out undesirables (sacrifice people you don't want to have too many of)
@Low stats you are literally comparing isnotreal and palestine maybe read some history books and you will know tht the war between this two was never about borders but about existing just like the war between the Americans and the red Indians one is trying to save their identity and race the other one is trying to steal it
