What was the underlying cause of the cold war?

I would say that this can be seen in two ways:

a struggle of two world views: capitalism vs communism

or

a struggle of two superpowers to have control over the other countries: the US and the Soviet Union (as it can be argued that the two countries were not satisfied that other countries had the same system as they, they also sought control over them).

This is what i found on google “the first mobile phone call was made 40 years ago today. on april 3, 1973, motorola employee martin cooper stood in midtown manhattan and placed a call to the headquarters of bell labs in new jersey.” i hope this you for what your looking.
