Former Energy Secretary Dan Brouillette defended the ongoing U.S. military operation in Iran during a Friday appearance on NewsNation's "The Hill," despite rising global crude oil prices.

Brouillette, who served as Energy Secretary under President Trump, characterized the surge in energy costs as "short-term pain" that would yield "long-term gain." He made the comments as global crude oil rates have spiked in response to the military action.

The former cabinet official suggested that the administration views the current situation through a broader strategic lens, though he did not elaborate on specific long-term objectives or timeline expectations for the operation.

Oil markets have reacted to the military developments with increased volatility, as investors and traders assess potential impacts on global energy supplies and regional stability in a key oil-producing region.
