How will Saudi Arabia respond to continued U.S. leaders' discontent
with its support for terrorism?

There is no evidence that Saudi's leaders support terrorism

If anything they have more to lose than the USA from 'fundamentalism'

Frde, 

See this answer for example: 
Has Saudi funding for Wahhabistic Madrassa schools been affected since 9/11?

Even paraniods have enemies, you know.

Interesting

I know it sounds odd, but funding schools and mosques does not
necessarily mean that you agree with what they are teaching and
preaching.

My impression is that the Saudi nomenclatura went along with the
religious schools as the line of least resistance.

Since those schools seem to give a pretty strange 'education' it is
not surprising that they churn out unemployed (and unemployable)
alumni - creating yet another problem for Saudi.
