Earlier quoted context omitted.
How is that hard to understand? Why should we treat US citizens visiting the EU better than the US is treating EU citizens entering the US?
Why not? the US has the death penalty, I wouldn't support the death penalty for an American in Europe. I'm not entitled to free medical care in the US, I would have no problem with an American using my health service, if needed. If it is just a tit for tat, that just makes everyone worse off. The supposed stated aims (security) seem suspect between 2 blocs that really should be able to work together.
Unsurprisingly, the one that provides cover in the US is significantly more expensive.
