Christians are forever

 Atheism - a disbelief in the existence of deity 
Letter to North Korea
Letter to the North Korean people

Greetings to our brothers and sisters of North Korea.  It has come to our attention that your government is threatening to launch missiles armed with nuclear warheads to neighboring countries including our own.  We regret to inform you that if any such missile is destructive to another country, including ours, we will be forced to do the following:

destroy your government
destroy your military
 destroy all offensive weapons.

The estimated time required for the majority of this cleansing would be about two to four weeks and the time required to clean out the leftovers would run somewhere between eight to sixteen weeks.

After that we would be pleased to join you in establishing a new government that must include for its citizens the following:

freedom of religion
freedom of speech
and the right to bear arms

Thank you and we look forward to working with you. 

The people of the United States.
May God bless you all.

ps: Nuclear weapons will not be required for these actions.
This is a sample letter which should be sent to the people of North Korea from our government..
