The Russians are capable of the leaks, but I am not convinced they are the perpetrators.
Its interesting to think that IF it were the Russians, what would motivate them to want to help Trump win and Hellary lose. If that was indeed the goal, it implies to me that Putin believes that a Hellary presidency would be bad for Russia and a Trump presidency would be better. This would run contrary to the idea that a Hellary presidency would further demote the US on the world stage while a Trump presidency would strive to “Make America Great Again”.
Only IF it were the Russians, and that’s a big IF, Putin, call him a bully if you want, would seem to think that a strong US, with sane foreign policy, is better than a weak US with childish foreign policy.
See #60 for some interesting ideas.
Under a second Clinton administration, the deterioration of the American military in all respects will continue. Only the United States can give any strength to NATO pledges to protect the Baltic States, Poland, and even Norway. The other NATO militaries, with the exception of Poland, are even weaker than ours. If and when Putin decides the time is right to take back what was lost in 1991, NATO will be impotent to stop them. All of Hillary's squawking and hand wringing will be a mere manifestation of American and Western weakness.
Additionally, the results of this election will further divide this nation. A large portion of the anti-liberal opposition is out of the "corral" of the Republican Party establishment and the Fox News/National Review/Westwood One/Salem Communications moderate/ conservative media. Trump has radicalized the base. The voice of the future anti-liberal opposition may be Alex Jones, and not Rush Limbaugh.
This will have the effect of turning the United States into two increasingly hostile camps. This is not always a good thing. French rightists opposed to the leftist government of their country had a saying, "Better Hitler than Blum." Will American rightists, somewhat enamored of Putin's traditional values and Orthodox Christian faith, be saying. "Better Putin than Hillary"?
