@FrancoisPrague @MeanwhileinCanada What next? If Trump continues to threaten Canada OR Greenland, I suspect this:
1: the rest of NATO invokes Article 8 to expel the United States
2: If Trump persists in his threats or appears to be ready to invade for real, invoke Article 5 and make it plain that an attack on one is an attack on all.
3: Get hackers working to gain access to those kill switches on US warplanes. Shut 'em down if Trump actually attacks.
