Was the U. S. policy of containment a success or failure?

The short-term division of Korea along the 38th parallel was a great success for the policy of containment, as communism did not spread into South Korea. In 1954, SEATO (South East Asian Treaty Organisation) was structured as a copy of NATO. Communism had been avoided in South Korea and the UN was seen as a great success.

Explanation:

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
