History of treaty- in 1955 American president moved forward to sign this deal but chief of Soviet did not approve it, if it will be approved then we would not see cold war, but in 1992 when Soviet come to collapse they have realised importance of this treaty. So they signed treaty and finally it came in effect in 2002, since then it has helped to clear many confusions amongst member nations. America was trying to widen the limit of this treaty in previous years, it was also trying to include China in this treaty but suddenly it has pulled of treaty. This will eventually create need of a new treaty or we are going to danger the world.
Criterias of treaty - This treaty basically depends upon physical geography of countries. For example area of Russia is very long so this treaty also put more surveillance in the time of confusion in Russia.
Reasons of breaking treaty-America is saying that Russia was not providing enough surveillance of its area so that's why it has broken the treaty.
