That's a government person calling for an attack on another government. This is a citizen calling for an attack on a group of individuals, government-involved or not. It's not even remotely the same.
It's literally illegal to give death threats (not that I think this qualifies as a particularly serious one). But that's the difference between this and your argument with politicians rattling sabres. (Just to make it clear, I don't feel so strongly about the whole situation, but I do think making false equivalences is misleading)
