The Greatest Depression.

Make American Great Again. Yep.

Only one small deviation from your analysis

T.H.E.Y. do not care for money.
T.H.E.Y. want control.

Money gives them power, which makes them think they have control.

T.H.E.Y. want darkness to descend on the world.
T.H.E.Y. want Lucifer to win.

T.H.E.Y. can't get these goals by just killing people, people reincarnate.
So, T.H.E.Y. work at making everyone's life miserable. To sew dissension and controversy. To make everyone feel as if God has abandoned them and they lose hope.

T.H.E.Y. have been at this a very long time.
