attitudes like that is why the world is so fucked up curahee
deal with it
It's an observation of fact, not an "attitude."
Humans are a living species on this planet, all species (individuals or teams of individuals, up to the nation state level) will compete with each other for resources. The ultimate expression of that competition is violence and war. Sure, as long as resources are available they can be dealt with through business, but ultimately business leads to war. Add human society's multiple levels of technology, mythology, history and nationalism and it gets worse.
In this thread people have espoused Switzerland's neutrality, as an example of a people that can choose NOT to go to war. Do they not realize that the Swiss were one of the largest exporters of war and violence in history? "Switzer" basically means professional soldier in middle German. They were only able to remain neutral in WWII through that unique ability to deal on both sides to make the war more profitable for others (with them taking a cut.) They recognize the inevitability of war and maintain one of the most the most militarized society in the world.
People in this thread have bragged on the Jeffersonian idea of business over war. Which is great and all, but one of Jefferson's first acts of his presidency was to go to war to protect America's business interests, "Shores of Tripoli." Later, He purchased vast amounts of resources from the French which led the war and subjugation of entire societies.
Whether you choose to think war is necessary or not, or whether you believe a particular war is justified is never going to stop people from waging war on you.
Competition for resources (and war) are biological fact. This is born out through the history of not just man, but all living things that have ever been.
