All of that is true. However the US is superior to Russia in every way - economics, military, etc. They need to get along with the US to stay a major player and both countries can do a lot of good in removing worldwide threats.
They may well have meddled in the election, but they are not alone. In my opinion the greatest threat is China. They have stolen huge amounts of military, space, and technology secrets and their spies are buried deep into our government and industry.
Frankly I suspect it is China who hacked the DNC computers and they were able make it look like Russia or some other. They have been known to do that before. Remember a few years ago when they shut down Wall Street by cyber means and then apologized says a mistake had been made.
One problem with China, is they have a border with Afghanistan. Any time they want, they can stir up trouble there, and drain the US and Australia even further. It is past time to wrap up the expensive Afghan adventure.
