While I am critical of Ukraine being in talks to join the EU (which IMHO it shouldn't), I am quite happy that we in EU kind of have built good relationships with Ukraine - military drone construction knowledge and expierience will become a key technology field, as cooperations between Ukraine and Europe after the war (however that will look like) will probably strengthen europes defense capabilities.
Because given the current state it is in, it will receive net-payments from the other EU states for decades and we are already on a descending path economically in the EU. No more foreign subsidies and helps until we got our own ship back on course.
