I have learnt this phrase long before.
like "To some extent ,I agree with you"
but what's the meaning of "to the extent that+ clause" ,any word can be used in its place?thank you:)
eg:
In his January 2004 State of the Union address (to the extent that multilateralism was addressed at all),
1.to the extent that
2.at all (

nly know it can be used in a negative sentence or a question)
please explain these two phrases for me ,
thank you
