This bill if passed and enforced could be the beginning of a very deep change of the structure of the internet. Since the internet developed mainly and the infrastructure relied on US companies, it was excepted that US will play nice and will not use this to cause problems. Of course, Snowden showed us that even American are not safe. Now you are basically telling each government that we will use our tech advantage against anyone we seem an adversary. And I think WMD stories may still be fresh in the eye of any decision maker and would take this as a security issue. This might propose the actual Balkanization of the internet, as each country or group of countries might think that seeking independence from US infrastructure dominance is a national security interest. I think this might have much deeper impact that the obvious and short term effects proponents see.
