Cold War Five: America's Role Abroad

The idea of COLD WAR FIVE, while not a new hypothesis, is the analysis of the traditional hegemonic Cold War in four stages:
1. Rise of the Bolsheviks and Russian Civil War
2. Costly Second World War and subsequent Russian expansion
3. Nikita Khruschev's "De-Stalinization" efforts 
4. Principles of Detente and eventual collapse of the Eastern Bloc

The 5th installment of the Cold War is here. 

For the first time since 1945, the United States now faces a looming threat from multiple major powers. Through the lens of historical context, it can be argued that the tension currently faced is an evolved and expanded version of the traditional hegemonic battle that capsulated the 20th century. 
What types of political or military gambles towards escalation are we willing to take? And, how equipped are we to meet the needs of modern national security? 
Through expert analysis we hope to crack the enigma that is great power struggle
