You’re missing the point of this. Right now all the aid Ukraine is getting is dependent on piecemeal decisions, which if Europe and America get bored, can dry up extremely quickly. Russia is banking on that and is investing heavily to try and produce this outcome.

A statement comitting to long term aid undermines that. And at least somewhat shores up Ukraine’s aid. I don’t know how binding this declaration is to any party but as the article says: it is a signal that the West intends to keep up the aid for as long as Russia keeps up the invasion.
