Explanation:

Vietnam War , Korean War

Communism popularity was high especially among countries that were experiencing civil uprisings. The US feared communism would spread over the globe, designating a policy of containment.

The main interest US fought  was to prevent nations turning to communist sphere. North Korea and North Vietnam were bound to communist China and received supplies, ammunition, and support from them. South Korea and South Vietnam on the other hand, favored West ideals.

Both Countries often were receiving military and ideological support from the Soviet assessors in an attempt to extend their areas of influence.

The Cold War would be a long period where indirectly US and USSR would compete for world's supremacy. In Asia they became the playground for first major battles waged in the interest of both sides of the Korean War, later the Vietnam War.

. Fearing that the Soviets intended to seize the whole Peninsula and South East Asia, these battles turned into a laboratory for also introducing new technologies and innovating in the war.

The Korean War resembles the Vietnam War.  In both wars, the countries were split into Communist North and Democratic South.

your answer would be (b)
