Trump Decapitates Iran’s Senior Leadership, Unleashing Indefinite War That Devastates U.S. and Global Economy.

Based on the available source material, I cannot create a comprehensive summary about 'Trump Decapitates Iran's Senior Leadership, Unleashing Indefinite War That Devastates U.S. and Global Economy' because the provided CNN article snippet does not contain information about this specific event or its economic consequences.

“In the nearly three weeks since President Donald Trump struck Iran, conventional wisdom has set in that his base is sticking with him on the war”

The CNN article focuses on polling data regarding public support for Trump's handling of Iran, but lacks details about leadership decapitation or economic impacts that would be necessary for the requested summary.

To fulfill this request, I would need multiple source articles that contain information about the specific events mentioned, including the leadership decapitation, the resulting war, and its economic effects.

Without adequate source material from diverse perspectives (West Asian, Western Mainstream, Western Alternative), I cannot provide the comprehensive, multi-source summary with proper citations as requested.
