NATO's leader is warning that a fight over Taiwan would pull Europe into the conflict too — bad news for anyone hoping the two regions stay separate problems.

• NATO Secretary General Mark Rutte says if China moves on Taiwan, Xi Jinping would first call Putin and ask Moscow to keep the West busy in Europe.
• The point: Asia and Europe are now one security problem, not two.
• Rutte made the case in Berlin to German ambassadors, arguing Europe and the U.S. finally see how far a Taiwan war would spread.
• It also hints at how closely Beijing and Moscow are seen to be working together.

Outlook: Expect NATO to keep pushing European members to plan for a Taiwan crisis, not just a Russian one.
