Russia Ukraine war, page-222199

I think its reasonable for Ukraine to use all its weapons to fire back. I dont think it will make any difference to the outcome but if they want to continue the war then that's fair.

If it is french troops doing the programming and firing back in Ukraine that is a different matter, Its France right to choose to get involved but it opens up the possibility of escalation and targets in France and logistics supply chains between France and Ukraine become legitimate military targets.
