In the end, US doesn't need encryption backdoors because most chat and email protocols are not end-to-end encrypted and the TLS data streams are decrypted in the datacenter owned by US companies.
If you wanted to make the corresponsing strong argument for Chat Control and its ilk, the EU just wants (the juicy part of) what the US already has. The remote root level control of most end user devices is not under EU juristiction. So they naturally want companies operating in the EU to give them one piece of access to the presentation layer, too.
This argument is what one must be prepared for, the encryption itself is less relevant..
