Stranger and stranger!

I quote from the UN News Center:

2 April 2013 – The United Nations General Assembly has approved a global arms trade treaty that failed to achieve unanimous support last week but garnered the support of a majority of Member States when put to a vote today. 

The resolution containing the text of the treaty, which regulates the international trade in conventional arms, received 154 votes in favour. Three Member States – Democratic People’s Republic of Korea (DPRK), Iran and Syria – voted against the decision, while 23 countries abstained.......

“The Arms Trade Treaty asks States to explicitly consider the risk that an arms transfer could facilitate serious acts of violence against women and children before allowing it to proceed,” Susan Bissell, UNICEF’s Chief of Child Protection, noted in a news release. “This is critical given that weapons are now one of the leading causes of death of children and adolescents in many countries, including many that are not experiencing war,” she added.

The UN Special Adviser on the Prevention of Genocide, Adama Dieng, welcomed the inclusion in the treaty of a prohibition on the transfer of arms which would be used in the commission of genocide, crimes against humanity and certain war crimes and called on States to act quickly to apply this prohibition, pending its entry into force.

And from the Voice of America, April 03, 2013:

The new global arms trade treaty was overwhelmingly approved by the United Nations, with U.S. backing, but it was clear on Wednesday it faces a tough fight for ratification by U.S. senators who contend it could affect Americans' gun rights....... 

Washington was one of the 'yes' votes, but to go into effect for the United States it must win at least 67 votes - a two-thirds majority - in the 100-member Senate. Last month, the Senate supported a measure calling for the treaty's rejection even before U.N. negotiations on its text were completed. 

The powerful National Rifle Association gun industry lobby promised to fight against ratification. Several senators, mostly Republicans, quickly issued statements opposing the pact.

How could 34 or more senators side with North Korea, Iran and Syria. How could they oppose a treaty 

• to reduce gun violence against women and children, 
• to reduce the use of guns by those committing genocide,
• to reduce the use of guns during crimes against humanity, and
• to reduce the use of guns in war crimes?
