A tweet responding to Sean Parnell (Trump's pick for Secretary of Defense) with "Returned to sender. Sincerely, Iran." The implicit message: Trump's saber-rattling rhetoric about regime change and military dominance keeps bouncing back from a government that doesn't take the threat seriously. This sits squarely in the pattern of Trump's entire Iran policy being unhinged fantasy. He's been inventing regime collapses that never happened, bragging about nonexistent military dominance, and floating regime change scenarios with zero grounding in reality. Iran's response, dry and dismissive, suggests they're watching a man with no actual leverage perform theater.
