I said that each nation on this planet does what it wants, mostly, and it's hard to get a supervising authority that regulates (the UN?) effectively, since each nation does what it wants, except when coerced or ganged up on by others. If you think of each nation as an individual or a business which owns property, then you have the exact model of libertarianism. The population within any given nation generally operates under house rules (i.e. a household) - one nation (or nations) generally can't tell another nation how to run their own household or tell them what to do on their land.
The world is kind of fucked up. Look no further than that to understand libertarianism.
As for your links, it appears that laws guided by regulation within the given nation aided in catching the uranium smugglers. Is something wrong with that?
And every country should do as it wants . UN/US/France/etc. should not interfere because they are SOVEREIGN and the people there are responsible for their well/worst governance. And every country is responsible for it's own citizens. EVEN when you go free the Libyans or the Yugoslavians you are practicing aggression on a sovereign state.
Let me ask you this: If for example USA would end up in a revolution now. A real revolution that would have proof that it can change the country for the better , it succeeds but the supporters of the past governance are heavily affected by the reform and revolt violently. What should the government do? Fight? Then should China/Iran/other choose parts ? And if they do which should they choose? Or should they just start bombing the government forces because it represses it's own citizens? OR should the new, better government just give up the power?
I think they should stay put. And i think the revolutionaries should just fight the system from within not revolt. You revolt , you accept the risk , you are repressed you find ways to fight overtly , from within , You can't expect any government or power pillar to just give up it's grips without a fight , and it shouldn't give up without a fight.
And no the law didn't aided in catching the uranium smugglers PEOPLE DID . The law is just words on a paper. If you obey it or not , or enforce it or not is purely a choice , you make base on your moral values , religious beliefs , scientific believes/proofs , etc. You can continue to believe in the power of law , but always remember there are some , that don't , and then we go back to the only law that counts survival of the fittest/smartest/richest.
I'm not against law (agreement to use force) , but regulations that give birth to monopolies , or support failing business models , or save failing business , or repress "thieves" that don't deprive anyone of anything are regulations that i will never make the choice of obeying or enforcing.
