Try not paying your taxes, or paying fines, resisting bailiffs, and yet refusing to go to court/jail and see how things work outside the "primary school playground". You'll see it is all based on the threat of physical force, even if you can't see so. If violence is the last resort, is is by that measure the "foundation" of society, if not the basis.

That said, the international community is not "society". You can have all the treaties you want, the threat of violence comes when nations care to break them.
