According to Chris Terry from Electoral Reform Society, the fall of communism affected the world in ways as follows:
" A new focus on democracy and human rights as an outcome of foreign policy, rather than an attempt at containing the Soviets, no matter the cost
The end of wars in places like Angola, where the two sides were essentially proxies for the two superpowers
The US becoming the sole superpower and the creation of a unipolar world (though we are now, arguably, seeing the rise of additional poles) "
