Ukraine could soon fire Western-supplied missiles at targets in Russia. But don't expect that to tilt the war in its favor.

• Ukraine's allies look set to approve its use of their weapons on targets inside Russia.
• A growing number of NATO allies have backed the move, prompting the US to also reconsider.
• Ukraine could attack Russia's border forces, experts told BI, but it's no silver bullet.
