US President Donald Trump called Germany's trade and spending policies "very bad" on Tuesday, intensifying a row between the allies and immediately earning himself the moniker "destroyer of Western values" from a leading German politician.
Trump concluded his first official tour overseas on Sunday, which took him to Saudi Arabia, Israeli-occupied territories, Belgium and Italy for a G7 summit.
The foreign minister later echoed previous statements by Chancellor Angela Merkel, who over the weekend sent shockwaves through Western capitals by arguing that Europe can not rely completely on the USA or Britain.
Trump's dealings with Saudi Arabia, his refugee policy and stance on environmental issues are examples of issues that make the West "weaker", according to Gabriel.
"But the importance we give to these ties can not lead to us renouncing fundamental principles such as our commitments against climate change and for open societies and free global trade".
After a unsatisfactory G7 summit, German Chancellor Angela Merkel on Sunday made a campaign speech in a Bavarian beer tent, grumbling Europe's alignment with the USA and Britain. And then Trump gets huffy - as evidenced by his latest round of tweets - when they respond in kind.
"The times in which we can fully count on others are somewhat over, as I have experienced in the past few days", she repeated today.
"The president believes that seeing Europe and other NATO countries increase its burden sharing is a very positive thing for their own countries, for NATO as a whole and for the US", Spicer said, pointing to conversations at NATO and the G7 summits. "It is inappropriate that we are now communicating with each other between a beer tent and Twitter", he said in Berlin.
The decades-old US-Germany relationship appears to have taken a dip under Trump administration.
But if there's one thing we've learned throughout Merkel's near-12 years in office, it's to take her at her word.
