Second World war resulted in US dominating the scene. Vast technological changes were brought about. Every country wanted to be technologically advanced than the other. This led to scientific developments that paved way for many products. This boosted the economy. Arms were traded.
In both the cases,there has been interaction of people among different nations, this itself sets the tune for globalisation.
