Which is why we must never give Ukraine enough firepower to pose a threat to the Russian regime.

But that does not mean we can't arm them with long range stuff, just in fairly small quantities. A Tomahawk can't take down Russia. A Tomahawk a day raining down in areas away from the battle front--that can make Russia very much want to quit provoking them. Provide such weapons on the basis that the supply will be immediately cut off at status quo ante.
