It’s horrible to consider this angle, but this could turn out to be a blessing for many European countries. There is a massive shortage of labour in large parts of Europe. There are large, well integrated Ukrainian minorities already in many European countries and many Ukrainians are well educated (esp. in the much needed STEM fields). So not to put Portugal down but it is certainly to some point self serving and I could actually see competition between Euro countries for those people in the medium term.
