Isn't it an important difference that we're not killing people if we just shoot down missiles, but we are if we blow up tanks too?

It’s certainly better in my mind, who knows how Russia will take it. Even with missiles you are still interfering with the attacks. That’ll raise aggression against NATO.

> you are still interfering with the attacks

If we don't interfere with the attacks at all, then aren't we effectively letting them get away with attacking a NATO state? And if we do that, won't they get even bolder?
