I consider myself an optimist, but given that the US has been in 229 wars over it's 249 years since founding, it seems highly unlikely that there wouldn't be a "next war".
My point is that war is the worst thing that humans can engage in, and that the prevailing sentiment is that constant war is an immutable status-quo, and hence it's okay, there's nothing we can do except downvoting those fucking negativists.
There’s nothing peculiar about the US, every country or even tribe has fought many wars.
