How did Japan end up controlling China’s gateway to the Pacific?

Japan controls a 1200km chain of islands that sits across the Chinese navy’s main routes to the Pacific. In peacetime, Chinese warships sail through the gaps legally, but in a war, the Ryukyu Islands could become a giant wall. With China historically sensitive to being hemmed in by foreign powers, how has Japan managed to control the Ryukyus, and what impact does this have on geopolitical strategy?

How do nuclear powers decide to end the world?

If a nuclear missile launched toward the US, it would take 20-30 minutes from an infrared satellite’s first detection to the retaliatory missiles leaving their silos. The president’s actual decision window is compressed to around six minutes, within which they must decide whether the attack is legitimate and how to respond, effectively choosing whether to end the world. But how do these nuclear launch procedures vary from country to country, and what do they reveal?

Why do US defense companies influence geopolitics so much?

The US spends about a trillion dollars per year on defense, and more than half of that goes to contracting companies. The five biggest, like Raytheon, General Dynamics, and Lockheed Martin, take a third of all contract dollars on their own. But why does the US rely so much on the military-industrial complex, and what impact does this have on geopolitics?

Who actually fights America’s wars?

I’ve never talked about this before, but I’m a big music guy, and there’s a song I really like by this artist from Appalachia called Fey Fili, and she has a song called War Dog whose lyrics basically explore how working class families just like mine join the military for healthcare or school and in pursuit of greater opportunity, and what those people trade for it.

Why would the US want to take Greenland when it already operates freely there?

The US has been openly campaigning to acquire Greenland since 2025, even refusing to rule out the use of force against one of its own NATO allies to obtain it. But what many people don’t know is that the US military has had a substantial presence in Greenland already for decades, including its northernmost permanent military installation. So how is the US allowed to operate in Greenland, what impact has the current administration had on this dynamic, and what role does Pituffik Space Base have on all of this?

How and why would the US invade Cuba?

In January 2026, the US conducted targeted strikes on Venezuela that ultimately decapitated the country’s government, placing President Nicolas Maduro in US custody and providing an avenue for US businesses to expand their operations into a country that has been a key US adversary for decades. Just weeks later, the US launched an even larger operation in Iran to kill the country’s Supreme Leader and degrade its military and nuclear infrastructure. And now reports indicate that the US may be preparing to conduct military operations against Cuba. These events have many similarities that can give us tremendous insight into the current administration’s priorities and strategy, but the question is, knowing what we know now, how and why would the US invade Cuba?

How has Russia’s relationship with Cuba changed since the Cold War?

In June 2024, a Russian nuclear-powered attack submarine called the Kazan pulled into harbor at Havana, Cuba. It was joined by a guided missile frigate, a fuel tanker, and a rescue tug. US destroyers and unmanned surface vessels shadowed them the entire way in, and though the Pentagon publicly waved it off, that single port call was the loudest signal in a very quiet relationship between Russia and Cuba that has been rebuilding since the Cold War ended. We all know the stories about the Cuban Missile Crisis and Soviet patronage, but how and why are the two countries collaborating today?

What makes Eritrea the North Korea of Africa?

If you’ve heard of Eritrea at all, you’ve probably heard it referred to as the North Korea of Africa. This is a country of a few million people governed for the last 33 years by one man, in a very literal sense. Eritrea has no constitution, no legislature, and no elections, but it is now being courted simultaneously by Russia, Egypt, Saudi Arabia, and now the US. So what makes this tiny east African autocracy so attractive in the world of geopolitics?
