This is GPS, the Global Public Square. Welcome to all of you in the United States and around the world.

I'm Farid Zakaria, coming to you live.

Today on the show, world leaders gathered at the G20 summit in Rome this weekend to discuss economic recovery, climate change to fight against COVID-19 and more.

What were the successes and failures? I asked the man who led a G20 effort to rescue the global economy successfully the last time around.

A global plan for recovery and reform. Former British Prime Minister Gordon Brown.

Then it has been two months since the United States completed its chaotic withdrawal from Afghanistan.

I sat down with the lead negotiator of the peace deal with the Taliban, America's former special envoy, Zalme Khaliza.

Nobody is happy with the way the final phase of the withdrawal happened.

What went wrong? And what is next for Afghanistan? I will ask him.

Finally, Democrats have been scrambling for months to finalize President Biden's $1.75 trillion spending bill.

The biggest roadblock has been how to pay for it. I'll talk to a leading expert with a theory that says the big price tag is really not a problem.

But first, here's my take. Have we witnessed another sputnik moment?

The Financial Times has reported that China tested a hypersonic missile this summer, though China denies this.

General Mark Milley, chairman of the Joint Chief of Staff, compared the test to the Soviet Union's sputnik launch during the Cold War.

I don't know if it's quite a sputnik moment, but I think it's very close to that.

General Milley should dust off his history books. The Chinese test has nothing in common with sputnik, and saying so feeds a dangerous paranoia growing in Washington these days.

To recall, the Soviet Union launched sputnik the first man-made satellite to orbit the planet on October 4th, 1957.

Both the US and the USSR had been planning to launch satellites into space for years, and the fact that Moscow got their first was a huge shock to Americans.

Coming in the wake of multiple powerful Soviet nuclear tests, sputniks signaled that in the next frontier, space, the Soviets were ahead.

Sputnik was a revolution in the space race.

Hypersonic missiles, on the other hand, are very old news. A hypersonic missile travels at five times the speed of sound.

Starting in 1959, the United States and the Soviet Union deployed intercontinental ballistic missiles that traveled around 20 times the speed of sound.
