There are other charters and agreements in other organisations by member countries to ensure human rights etc. So as a country and globally, human lives will not go back to the savagery, nasty, short, brutish as Thomas Hobbes described in his book state of nature.
You just remind me of the old school days by mentioning Thomas. I read the Op thread like thrice but I don't seem to comprehend where he is heading until I read your comments. If what you said is actually related to what Op is talking about, then, you need to access the current living condition of people. I don't know the country you reside but disregard the UN and any other charter or agreements signed. Most of the agreements reached are detrimental to some countries and the human rights aspect of the agreement is not being regarded by if not all, the majority of the partaking countries.
Thomas Hobbes will be disappointed wherever he is now because what he thought his teaching has eliminated is gradually coming back with different approach. During the state of nature, the battle was between the strong and the weak but it's now between those that make laws and the poor masses. The laws are now meant to protect the people in authority and render ordinary society helpless.
