International Public opinion of the nuclear issues in Iran and North Korea

To more easily compare it I will make two examples of the same, such
as Iran to develop uranium with the legitimate goal to make weapons
that will endanger human. Similarly, North Korean uranium for the same
purpose and the same with Iran. The question is what the international
community to this case? I believe they will oppose, prohibit, even
hated the two countries. Few countries want to be friends with a
country that has a dangerous weapon, threaten the friends of their
own.
Now compare if Iran does not develop nuclear weapons proved. But the
world internasional treat Iran seems right to produce nuclear weapons.
Iran made by the international community as a country worthy of
suspicion because quite dangerous. Iran also symbolized a small child
who brought explosives from time to time will throw to anybody that he
likes.
What happens in Iran on International this treatment? Iran to be
excommunicated from the countries that the international political
map. Iran also receive treatment as a country that ought skeptical
because they are considered most dangerous. A punishment that is not
comparable to that received by North Korea, North Korea is not an
issue, or suspected, but has announced that the country's legal right
to develop nuclear weapons. International world seems afraid of North
Korea, but not to Iran. North Korea has no oil, but Iran has abundant
oil. Iran one of the countries that plan to destroy Israel but not
North Korea. If so, why the international community treats different
between the two countries? What is the actual mission behind the ban
and the threat this? Answer me, do not develop prohibited weapons
nuklirnya, provided that the country is not dangerous for Israel and
the United States.
Iran has not proven to develop nuclear weapons, but in some countries
such as the United States, Israel, Russia and others have
nuclear but there is no problem.
I really agree if nuclear weapons are prohibited, but the
restrictions must be applied to all countries without exception. If
not, then the future there will be many countries who secretly or
overt produce weapons as a form of anticipating. If this is true, then
the premonition of "doomsday" or the big disaster that will soon arrive,
Wallahu A'lam.
