^^^ Edward Snowden's first contract was his Oath of Office, to uphold the Constitution of the USA. When he realized, through his position in national security, that many other people who had take the same Oath of Office as he did, were breaking their Oath, and causing destruction of America through that breaking, all he did was to tell us all about what they were doing. So, essentially Edward Snowden is near the top as far as being patriotic to the USA.
If you read the Constitution, you will find that the US doesn't have any business running around the world and interfering in other countries. And if it is unclear in the Constitution, then the writings of both the Federalists and the Anti-federalists will clarify it. (These were the two main groups of people who set up the Constitution in the first place.) Both groups wanted to keep America out of foreign affairs.
All that Snowden did was to do his duty and show us all how there were many people in Government breaking their Oath to uphold the Constitution, at least in the spirit of the Constitution. Regarding this, Russia was changed by US government people and US banking people who supplied the Bolshevik revolutionaries with what they needed to overthrow the Russian government of 1916. Putin knows this, or at least now that Snowden prompted him to look at Russian history.
The US is against Russia for one major reason. The Bolshevik overthrow was intended to make a socialist one-world government way back then. But, along the way, Russia revolted against the criminals in the US government and banking system. That's the basic reason why the US is pushing Ukraine into a fight against Russia. Not because Russia is trying to forcefully take over the world. In fact, just the opposite.
