Episode notes
Donroe Doctrine Signals Imperial Posture
- Robert Armstrong argues Trump's 'Donroe Doctrine' frames the Western Hemisphere as U.S. sphere of influence and signals imperial posture.
- Markets don't necessarily punish geopolitical aggression because bonds and stocks can still price solvency and profits, decoupling ethics from returns.
Markets Price Cash Flows, Not Morality
- Markets can't be relied on to resolve political or moral dilemmas because they price future cash flows, not ethics.
- Long-term market health depends on rule of law, so imperial erosion could harm returns over decades even if markets ignore it now.
Resource Moves Produce Narrow Market Ripples
- Geopolitical moves spike narrow groups of stocks tied to resources or operations in target regions.
- Broader indices and large multinationals often absorb or ignore such shocks unless economic fundamentals change.
