不攻自破是指无须攻击，自己就会破灭。形容论点站不住脚，经不起反驳或攻击。

出自唐·顾德章《上中书门下及礼院详议东都太庙修废状》：“是有都立庙之言，不攻而自破也。”

那么不攻自破用英语怎么说？

Facts will eventually scotch these rumours. 

2.如果服务器证书中的通用名是与证书的其余部分一起验证的，那么这种攻击就不攻自破了，对么？
If the common name on the server certificate is verified along with the rest of the certificate, the attack is defeated, right?
