“When the Philistines took the ark of God, they brought it into the house of Dagon, and set it by Dagon.” (1 Samuel 5: 2)
A national god is something else than the Almighty. Fyodor Dostoevsky sketched a “national god” as something peculiar to nations. In his novel, The Possessed (also translated as Demons), Dostoevsky showed it to be an egotistical “god” which wants to impose its “truth” on everyone else. This is pre-eminently the situation with the Washington, DC (WDC) government. Tentative characteristics of the American “national god” include its being a tremendous busybody, wanting to tell everyone how to live their lives.
The U.S. government was once not too bad, until it got hijacked by busybodies. (This incidentally is the root for “old biddies” – they are, in other words, old busybodies.)
So we have a “national god” akin to a bunch of old biddies. But how do you actually define this “national god?” One aspect is a staggering volume of lies whenever it wants its way. This routinely happens when the old biddies are targeting some foreign nation. The WDC government will lie, and lie, and lie until it gets its way. And it must be its way. There is no room for conciliation. So, for example, when the old biddies decide that the Syrian government must abdicate within three months – then slam! The door is shut and the old biddy must get her way! There is no turning back! At this point the machinery of lies goes into high gear. A ridiculous story gets invented and is constantly repeated. This is called “the news.”
Dagon was the “national god” of the Philistines. It had the body of a fish but the head and hands of a man. Fish, which are cold-blooded and swim in water, signify an elevation of mere knowledge, distinct from worship of the Almighty. (Water generally signifies truth, and in the opposite sense falsity.) When the ark was placed in the house of Dagon, the head and hands of Dagon broke off and then it was only a fish. The ark destroyed the Dagon worship of its own intelligence. After its head and hands fell off, Dagon was revealed to be just a self-important fish. (Acknowledgement to Bible Study Notes (Vol. 3), by Anita S. Dole.

So a tentative identifier for what is the American “national god” would be Dagon. We see the characteristic of wanting to impose its own “truth” on everyone else, based on its egotistical estimation of its own intelligence. But when confronted by the Supreme Being (represented by the ark), we see that Dagon is only a self-important fish, and not really all that smart.
