The cyber domain emerged as a perfect platform for international struggle over power and influence. International powers are actively engaged in cyber proxy warfare due to the relatively low risk of escalation, various enforcement challenges, and the vagueness of international law within this realm. These indirect conflicts might lead some global powers to close or restrict their virtual borders to avoid or reduce the plausibility of cyber proxy warfare or unwanted foreign influence in general. The formation of such restricted networks, articulated in this article as “internet bubbles,” is already shaping within the realm of actors like Russia, China, North Korea, and Iran. The authors argue that liberal democracies like the United States might be at a severe disadvantage to fight against cyber proxy warfare due to legal and constitutional barriers. But at the same time, the emergence of platform governance and self-regulation might be proven as a new force within these proxy wars and reshape its boundaries.
