Ian Bremmer shares his insights on global politics this week with a look at Chinese warplanes, the Pandora Papers, and Facebook's major outage.

What is China signaling by sending warplanes into Taiwan's air defense identification zone?

Well, it's not their airspace. They've done this before. They do it a lot. In fact, on some days, a year ago, in the past, they've had over 20 incursions on a day. Over the last few days, it has been record levels, so clearly, they're agitated. They want to show that they're strong and assertive. Having said that, we are not on the brink of World War III. There is a greater chance of accidents happening, and that would be a really bad thing, but on balance, this doesn't cross any red lines between the two countries. I think the headlines are a little breathless on it.
