I agree. What people forget is Snowden didn't intend to end up in Russia. He wanted to go from Hong Kong (where he tought he would be safe, but realised extradition still was an option) to Ecuador. But he feared US would intercept his plane if he went over US/US allies sky. So his plan was to go from HK to Russia, then to Cuba and finally Ecuador.

Russia stopped him because US had cancelled his passport.
