I liked best the following line from Bibi's speech.

"Israel is not what is wrong about the Middle East; Israel is what is right about the Middle East!"

Here it is in context:

We’re proud that over one million Arab citizens of Israel have been enjoying these rights for decades.

Of the 300 million Arabs in the Middle East and North Africa, only Israel's Arab citizens enjoy real democratic rights. I want you to stop for a second and think about that. Of those 300 million Arabs, less than one half of 1% are truly free, and they're all citizens of Israel!

This startling fact reveals a basic truth: Israel is not what is wrong about the Middle East; Israel is what is right about the Middle East!

Israel fully supports the desire of Arab peoples in our region to live freely. We long for the day when Israel will be one of many real democracies in the Middle East.

But this one is a close second:
"Of those 300 million Arabs, less than one half of 1% are truly free, and they're all citizens of Israel!"
