Both the reasons (AIPAC + pricing Oil in USD helps finance our deficits) are why we were there. But both of those reasons have been severely weakened, to the point of probably being eliminated anyways:

1. After the midterms, we'll get a read on how much AIPAC is still able to buy congressmen.

2. Before Trump obeyed Israel and bombed Iran, we had the illusion of being invincible. But now, we are faced with the brut reality that we cannot guarantee the flow of oil through the Hormuz straight, nor almost anywhere else in that whole hemisphere. Even to Europe: Ask Putin how much drones have changed the game.

This really eliminates any remaining motivations to keep pricing oil in USD. Which removes most of the motivations for the world to keep financing our deficit.

At this point our best option is to just leave the region, and try to transition to renewables absolutely as fast as we can. Oh, and raise taxes on everybody, because demand for our bonds is going to crater.
