That is not quite correct, It is ALL Bernoulli AND it is ALL Newton. The classical rules of physics don't apply in half measures, they are both different measurements of the same thing. Take any wing of any shape and you will be able to account for ALL of the lift by measuring velocity and pressure around the wing (Bernoulli) and you'll be able to account for ALL of the lift by measuring the downward acceleration of air, they are not mutually exclusive.
