@ljs @oleksandr It is hard for democracies to be this kind of "aggresive" unfortunately. Plus, Putin would retaliate, with some terror attacks, and submarine cables cut. Still, it would be good thing.
Anyway, sending strong message would be enough, and there's still plenty of space for that. For example, sending half of czech military equipment to Ukraine now would be good thing (and strong message). We could rely on NATO shelter before rearming...
