THIS WEEK saw UK  Theresa May present European Council President Donald Tusk with a six-page "divorce" letter triggering Article 50 and officially beginning the Brexit countdown – a move greeted overwhelmingly with disappointment and frustration from the world's press reports The Week.

According to left-wing French daily Liberation, May's letter, with its repeated insistence on a "deep and special relationship", was "more conciliatory" than her previous bullish rhetoric

However, it adds, a Eurosceptic press and hardcore Brexiters means the UK is "caught up in a fantasy of a return to the glory of a colonial Empire" and "one cannot hide the fear" that they will try to scupper negotiations.

History will decide whether voting for Brexit was "foolishness" or "a bold act", says German daily newspaper Die Welt.

It mourns the end of the "strategic logic" it says brought European nations together while weighing up the impact for the bloc, saying that while Europe has coped with other crises, none has been as serious as Brexit.

Centre-right French daily Le Monde says May's phrasing was "almost sickly", but that at its heart was "utterly blatant blackmail".

In the US, the New Yorker struggled to accept the letter, which was "filled with so many false claims, so much cant, and so many examples of wishful thinking that it is hard to know where to begin".

The Prime Minister's vow to represent "every person" in the UK was "blatantly false" when the young, the college-educated, and the outward-looking all rejected, and still reject, Brexit", claimed the magazine.

"Many of them regard it as a willful act of self-destruction, and future historians will surely agree with them."

The New York Times says that Britain, "a nation famous for calmly carrying on", has done so – although for all the reassurance that those recession warnings over leaving the EU have not proved correct, "nothing has actually happened yet".

Adriana Cerretelli, in Italian business daily Il Sole 24 Ore, writes that Brexit "reflects the British obsession with regaining national sovereignty and defending its own insular identity on every level".

The EU and its "undeniable flaws" must certainly accept a portion of the blame for its unpopularity in the UK, she says, but at the heart of the referendum result was a "confused desire" to undo the choice made more than 40 years ago.

Confusion was also the watchword for Belgian daily Le Soir, which asked: "How will the UK be 'stronger' facing the world's powers alone? Or 'fairer' abandoning a slew of rights and the values which guarantee them?"

Once no longer part of the EU family, the UK will "worry about these questions alone", it says, adding: "From now on, it is 'us' and 'them'."

Newsroom,  believes the triggering of Article 50 was a sad day for Britain, the EU, and scores of thousands of transplanted citizens in the UK and Europe.
