Your comment confuses multiple points: * US requires visas for travellers from 5 EU countries, only ESTA for others. EU requires equal treatment of member nations. This is the point of the EU-USA discord * ETIAS is an electronic travel authorisation system similar to the ESTA, and applies to all travelers to the EU from visa-free countries. Practically ESTA and ETIAS are both e-visas. This applies to all countries, not just the US.
