The description of the interaction as a 'blow up' is part of the narrative presented by Larry Johnson in the web search results, but no other independent source corroborates this specific phrasing or description.

The specific detail that Caine told Trump 'No' and invoked his privilege as the head of the military is reported across multiple web search results detailing Johnson's account, but this specific quote/action is not corroborated by a second, independent source.

The claim mixes specific details (CNN reporting, April 18th date, Pete Hegseth) with a specific action (Johnson showing footage). While multiple web searches mention Caine, Hegseth, and the White House, the combination of all these specific elements being reported by CNN and shown by Johnson is only detailed within the context of the provided web search snippets, making it difficult to corroborate the entire composite claim.

The claim attributes a specific correction regarding Caine's advice to 'the Washington Post.' While web search results discuss Caine's caution regarding military action, the specific detail about the *Washington Post* correcting a February online statement is only present in the context of the provided evidence structure and lacks independent corroboration.
