WTAF? Would Trump actually fight (for Greenland)?

Denmark says US threats to take Greenland by force would ‘end’ NATO.  

Does NATO have any plan to deal with an ally-on-ally attack?  Which side would the UK take if it happened? Or is it all just about Trump’s “art of the deal”?  Former UK ambassador to NATO Lord Ricketts shares his insights.

The US was said to have finally offered a security backstop for Ukraine when the UK and France formally signed-off their intent to put boots on the ground for any peace deal.  But when you look at the detail, is there anything actually new there?

And why did a fleet of US special-operations aircraft fly into the UK this week?  Was it just for the seizure of an oil-tanker, might it have something to do with Iran, or is it all an attempt to distract from something else?
