This week marks the 40th anniversary of President Richard Nixon's historic visit to China at the height of the cold war. The presence of Nixon in Beijing had changed the world.

But with the end of the Cold War, America started to look for new strategic rivals to keep its military industrial complex alive and to sustain its global leadership. The rise of Asia along with the ascendance of China as the second biggest economy help transform the US national security strategy and prompt its pivot towards Asia after beating a retreat from Iraq and Afghanistan.
