Bonus Haggadda d’var torah! (or a 1st if you view the one above as a d’var torah on Parshas Va’era)
We say “Bechol dor v’dor omdim aleynu l’chaloseynu…” In every generation they try to destroy us, only to have HaKadosh Baruch Hu save us from their grasps.
The Avudraham says that in every generation Hashem creates such an environment so that he can save us. By doing so each generation can see firsthand the hashgacha of Hashem
According to this pshat we are saying praise not just for the salvation, but for the fact that they make such attempts as well. Since due to these attempts every generation is able to see the protection Hashem gives us.
