Listen here, JerkFace! I actually agree with you a little, this time. Putin did what he could to both bring on Brexit, and elect Trump, as well as numerous other things that you or I will never know.
That being said, the US does this all of the time, and so does the UK, China, and many others. I am not excusing any of their actions, just agreeing that all world powers want elected people in other countries who are 'allies' and they do things, whether it is moral or not, to get their people elected.
