Without a doubt, Putin shouldn't cooperate with President Obama over Edward Snowden. Snowden revealed unconstitutional spying by the NSA on the American people and shouldn't be punished for doing so. He should remain in Russia under asylum and as far away from Obama as possible. The NSA snooping programs should be stopped immediately.
Snowden did the right thing. He saved America by exposing this massive intelligence programs. None of the information he leaked can be used to help a terrorist. The information he leaked contained things that the government does not want us to know that we should have known. Now Obama wants Putin to not give Snowden asylum but Snowden needs it and I myself would be willing to help him. He's a hero.
