I make the assumption Donald doesn't know about or care about any previous agreements between the US and any other country.
I also assume that Donald won't honor any agreement at any time if it doesn't benefit his personal opinion on any given day.

So Trump writes he doubt NATO would back USA if requested?
Can *anyone* help the rambling lunatic remember history correctly when we (NATO) have aided the US when asked to?
This is shameful, given all the brave fighters that have already assisted and made the ultimate sacrifice.
Shame on DJT.

"It is completely pointless to talk about the US seizing Greenland. USA has no right to annex any of the three countries that make up the Danish Realm.
Greenland and its people have made it clear they are not for sale and called on Washington to stop threatening people."

Using internet.nl I was surprised and saddened when I saw that email security at Apples iCloud service seems a bit stuck a decade back in time, compared to Cloudflare & Microsoft, among others. So I wrote this article about it.

Rotten Email Security @ Apple iCloud?
A long time ago, like back in 2015-ish, ACLU used a service created by Einar Otto Stangvik from Norway called starttls.info (doesn't exist anymore), based on my idea.
