Interview with Professor Phillips O'Brien
Some points I gleaned from the interview:
1. No such thing as a "Great Power". Time and time again, history has shown great powers losing conflicts they started. So, what makes them so great?
2. Iran-US: What would victory look like? For Iran, regime survival is all that would be required to consider it a victory. On the other hand, for the US, regime change in Iran is required. Anything less would have to be considered a loss.
3. With so many US assets tied up with Iran, the ability to defend Taiwan is severely curtailed - not that Trump is inclined to help Taiwan anyway. That said, it would be no cakewalk for China and they should think very carefully before attempting an invasion.
4. Having lots of military assets is one thing. The capacity to support them in a conflict is a different thing. This is being demonstrated right now, as the US scrambles to increase production of munitions.
5. European countries won't be able to count on US help. They need to standardise weapon system designs. The US has about 30 "systems", i.e. one tank, one artillery piece, one main class of destroyer, one standard rifle, etc. European nations have about 130 different systems and some consolidation is needed if they are going to defend themselves as a group.
6. The outcome of the war in Ukraine will determine the future of Europe.
7. If there is no regime change in Iran that results in a government that is at least neutral, if not actually friendly towards the US, the stature of the US on the world stage will be notably diminished.
