“why arent the other members of the EU helping Italy with logistics and medical personnel”
Because they are individual countries and are keeping their logistics and medical personnel to take care of themselves.
Unlike China or the USA, the EU is just a loose confederation, not a country. So each country is taking care of itself
The UK left the EU because it was ceding too much of its sovereignty to Brussels. The European Parliament makes a lot of decisions for EU members. The EU is far more than a loose confederation. They even have their own EU flag.
Also, you seem to have missed a bit of my sarcasm. Why arent these countries helping their neighbor and fellow EU member? When the chips are down, it seems it is every man for himself. If Canada were experiencing what Italy is going through now, you can bet the US would help. Europe and the EU are showing their true colors in this crisis. Not pretty.
