Didn't Canada just a few months back say India's spies killed a Canadian politician who held anti-Indian views? Or something close to that effect? Was in the news for a while with tensions raised. If a nation like Canada is saying things like that, I can see other, weaker, less alliance-protected nations being overzealous in their safeguarding against the such spycraft. More than likely they're just being murderous for the sake of being murderous, but they have a clear example they can point at as the reason for their actions.
