Short answer, yes. The concept of "foreign governments" is very US-centric. This tracking is not a US-only concept and the connection of these data points is already being used in non-US markets by companies which cross these boundaries. The only differences with each market is the number of signals available for capture. For example one party operating in the US is capturing DNS activity while in Brazil they are capturing telecom data.
So Vladimir Putin can track all US and EU politicians? Surely they might be interested if someone explained it to them in a way they could understand. Are there any limitations on what countries can acquire the data?
