Ukraine is fighting valiantly against an invading military force - Russia. With the recent 'annexation' of 4 regions in Ukraine, Putin has raised the stakes, he needs to be stopped NOW. The West needs to give Ukraine exactly what they are asking for, despite the cost, and the UK should lead on this.

The future security of Europe, and the wider world are at stake, Putin appears to be trying to reinstate an Empire, and we cannot allow this.
We need, in the West, to send everything we can to defend Ukraine, in terms of military hardware and munitions. The Ukrainian armed forces have proved themselves strategically brilliant, given the right equipment hopefully they will be able to drive the Russian forces out and regain what is rightly and legally theirs.
