Nagasaki and Hiroshima mayros sent letters against the US's nuclear tests

Palatine, IL
The National Nuclear Security Administration stated it has conducted a nuclear test sometime from October to December and another from April to June.  The nuclear bombs are potential very potent killing weapons which have not been used since the WWII.  

The Hiroshima mayor Kazumi Matsui send a letter to President Obama and Ambassador John Roos denouncing the tests.  The letter claims that the tests indicate the US is still trying to keep the weapons and they violate the Administration's "nuclear free world" principle.

Independent analysts say the US has spent more than $61 billion dollars for nuclear weapons. 

The Nagasaki mayor Tomihisa Taue and house speaker Hiroyuki Itasaka the tests 'tread on the hearts of the victims of the massacre' and asked President Obama not to repeat nuclear tests again.

I could not find the letters sent to the Obama Administration and there hardly no articles on this issue.  I will be adding more to this when more info will be available.
