Or has God ever before tried to deliver a nation from the middle of another nation, accompanied by judgments, signs, wonders, war, strength, power, and other very terrifying things like the Lord your God did for you in Egypt before your very eyes?

the great judgments you saw, the signs and wonders, the strength and power by which he brought you out – thus the Lord your God will do to all the people you fear.
