> that they use because they can't get the artillery shells that they need

That used to be true, but I don't think that the case anymore. UA is now striking logistics ~150KM behind the contact line with drones. Regular artillery can't do that. Guided rockets maybe could, but they'd be more expensive and come in smaller quantities.

> US is currently able to wage a war 6000 miles away from its shores

For a rather restricted use of "wage a war". They did not stop Iranians from doing their thing. Bombing alone does not have a history of winning wars.
