Trump made a clear choice: return to petro-imperialism
Trump made a clear choice: return to petro-imperialism. To understand what just happened in Venezuela, look at oil politics and U.S. foreign policy.

For decades, Canada integrated into US supply chains for car manufacturing so both could compete globally. As Trump raises tariffs and doubles down on inefficient gasoline-powered cars --> Canada builds its own EV industry, looks to trade globally, and US firms lose a market.

The US seeks price floors with allies to build ex-China mineral supply chains.

I just used the example of Harvard at a roundtable on international relations at this moment--that Trump sucks at coercive diplomacy as he can't accept yes as an answer. He is always asking for more.

New from us: The average EU citizen spent EUR880 on fossil fuel imports in 2025, as gas imports increased and the U.S. became the largest supplier. Slow progress on electrifying transport and buildings as well as building wind power are harming the bloc's economy and energy security.

Huh. I guess the @nytimes.com is estimating crowd size in protests after all. Hope they'll do it again when it matters, when the crowds are even bigger. Crucial signal to those on the sidelines.
