Decisive or Distracted: The Effects of US Constraint on Security Networks

The rise of China as a global power has been a prominent feature in international politics. Simultaneously, the United States has been engaged in ongoing conflicts in the Middle East and South Asia for the past two decades, requiring a significant commitment of resources, focus, and determination. This paper investigates how third-party countries react to the United States’ preoccupation with these conflicts, particularly in terms of diplomatic co-operation and alignment. We introduce a measure of US distraction and utilize network-based indicators to assess diplomatic co-operation or alignment. Our study tests the hypothesis that when the US is distracted, other states are more likely to co-operate with its principal rival, China. Our findings support this hypothesis, revealing that increased co-operation with China is more probable during periods of US distraction. However, a closer examination of state responses shows that democracies distance themselves from China under these circumstances, while non-democracies move closer.
