On Monday, the Biden administration announced it would provide up to $6.6 billion from the bipartisan Chips and Science Act to allow the Taiwan Semiconductor Manufacturing Company to expand its existing facilities in Arizona. The US goal is to ensure that TSMC, the world’s lead maker of advanced microchips, can boost semiconductor production on US soil. Taiwan’s tech titan now produces the overwhelming majority of the world’s advanced chips.

For all countries with advanced manufacturing capabilities, future chip production will be crucial for both economic dynamism and national security, because semiconductors will be an indispensable component in everything from electric vehicles to consumer electronics to satellites and advanced weapons systems.

Monday’s announcement marks a political victory for President Joe Biden, who can now claim he’s adding a “Made in America” label to the world’s most advanced technologies.

There is an important security implication from this announcement, one that Taiwan’s government may not like. TSMC remains at the heart of the island nation’s “silicon shield,” the protection that semiconductor dominance provides Taiwan by giving the United States good reason to protect it from Chinese attack. Shifting more of TSMC’s production to Arizona reduces that incentive.

Listen: Elon Musk, the world’s richest man, made his fortune-breaking industries—space, cars, social media—and is now trying to break the government… in the name of fixing it. But what happens when Silicon Valley’s ‘move fast and break things’ ethos collides with the machinery of federal bureaucracy? On the GZERO World Podcast, Ian Bremmer sits down with WIRED Global Editorial Director Katie Drummond to unpack the implications of Musk’s deepening role in the Trump administration and what’s really behind his push into politics.

Last week’s arrest of Istanbul Mayor Ekrem Imamoglu sparked the largest anti-government rallies in a decade and resulted in widespread arrests throughout Turkey. Nearly 1,900 people have been detained since the protests erupted eight days ago.

Alarm bells are ringing ever more loudly in South Sudan, as Vice President Riek Machar — chief rival to Prime Minister Salva Kiir — was arrested late Wednesday in an operation involving 20 armored vehicles at his compound in Juba. He was placed under house arrest, a move that is fueling fears that the country will soon descend into civil war.

The Trump administration has dropped multimillion-dollar bounties on senior Afghan officials from the Haqqani network, a militant faction that carried out some of the deadliest attacks on American troops but has now positioned itself as a moderate wing within the Taliban government. But why?
