The Russians and others have just discovered that our democracy, and maybe all Western democracies, can be manipulated pretty easily with fake news and phishing expeditions (maybe a little bit and maybe a lot) and this is a dangerous thing. My own reaction is that I don't expect another country or interests therein to piously obey our laws concerning election influence. So if Chinese interests donated money to a political campaign, I regard it as self-interest on the part of the Chinese. I can hardly demand that the US be free to meddle in other nations' politics but be considered immune from similar attention.
Although, in the past we made covert and not so covert efforts to influence elections, but it is natural part of foreign policy that all nations engage in a double standard when it comes to actions they perform against others as opposed to actions others perform against them. We willfully bomb other countries that we have people we don't like. Does that mean we shouldn't be bothered, if another country decides to bombs us?
