The USSR’s expansionistic practices subverted pre-existent leadership structures in areas that came under their rule while the USA strove to ensure free societies in which the citizenry enjoyed their liberties responsibly. This therefore was the basis for ideological differences hence global polarization. The National Security Council saw Kremlin’s challenge as ideological and territorial. To counter this influence in Eurasia, the National Security Council proposed to: strengthen its economic and military force; enforcing her ideologies through economic and political empowerment to reaffirm the need for systemic freedom; ensuring that the Soviet appreciated the importance of these liberties.
Splitting countries in line with the different ideologies propagated by the two protagonists was done to counter ideology propagation. The need for freedom would increase in the regions annexed by the USSR, hence a progressive decline of USSR ideologies and influence in these regions as witnessed through the independence of Czechoslovakia, Herzegovina, Bosnia etc. Military action was used in cases where human rights were undermined i.e. North Korea invasion of South Korea in 1950. Militarization was used as a deterrent to foes as ideologies are propagated.
In 1945 Vietnamese leader Ho Chi Minh seceded and declared independence from France. Later, he frustrated peace talks with France and declared war of independence. As the cold war escalated, the USA extended financial support to capitalist France while Communist China and Russia availed arms to the Vietnamese guerilla. Ideological differences and displays of military might, split Vietnam into the communist backed north and the capitalist backed south. Ngo Diem rejected American military presence and democracy south Vietnam and winsurgents allied to Ho Chi Minh from North Vietnam. War was declared against the insurgents in North Vietnam in the Viet Cong. Pressure from civil rights groups and demonstrations from students from Madison University made the government forestall and withdraw the troops from Vietnam.
