This is largely consistent with historical US views on international law. In 2002 the US passed the American Service-Members' Protection Act, which states that if any US service member or elected official is criminally prosecuted by the ICC, the president can use "any means necessary" (i.e. invading the Hague) to ensure their release.

In general any idea that international law is relevant except as a tool for the West to provide moral justification for its actions when it's convenient to do so is naive. At least the Trump administration being more vulgar and crude in expressing its disregard for international law compared to previous administrations may open more people's eyes.
