The reverberations after the American presidential election will echo and possibly overtake the reverberations after the Brexit referendum.
In both cases the people have spoken.
In both cases, the predictions by pundits and pollsters were duly overturned.
In both cases the outcome was definitely one that the political elite in each country could not even begin to imagine.
And now, on the morrow, all the dire predictions of the past weeks come home to roost.
Both the Brexit win and Trump's victory come from the bedrock of the society that was called to vote. Brexit showed that a majority in Britain did not believe in the European dream as spouted by successive leaders. What the British voters saw around them did not mirror the Brave New World of government and Brussels propaganda.
As a result, the British electorate took a huge gamble, one that can cost its economy dear. But that was the decision the electorate took and, as Prime Minister Theresa May says, "Brexit means Brexit".
In the United States one must not forget that apart from the leaders two big parties exist and these parties have their power base, their seats in the various legislatures, etc. It is Donald Trump's victory but it is also the victory of the Republican Party. Its party machine proved to be more efficient than that of the Democrats.
As in the case of Brexit, there were many internal issues at play and a non-American (as a non-Briton in the case of Brexit) cannot be expected appreciate.
In the case of the US, the people who came out in their millions to vote for Trump showed they had had it up to here with the Clinton dynasty, just as a few years ago the same American electorate showed the same anger at the Bush dynasty.
Donald Trump is the first US president with no experience as a legislator. He is not a politician - and his countless gaffes, verbal overdrive, misogynistic outburst, racist undertones bear this out. None of these can be glossed over or excused.
But what the world today is sincerely afraid of is of an America that will be radically different from the one we know today. An isolationist, protectionist, maybe even a war-mongering America that puts world peace in jeopardy.
Seen from Europe, Trump's victory is a call to action. It has already been pointed out that the Brexit result last June was a call to action. No such action has been taken. The British people voted against a weak, over-powering, EU led by an unelected Commission.
We cannot say that the Americans voted the way they did as a reaction against Europe. They had other battles to wage - abortion, immigration, an overbearing ruling class, complaints by so many citizens who felt they had been overlooked...
But the effect of the Trump victory will be felt by Europe. Unless Europe gets its act together, it can suffer in the coming future. On the other hand, this is Europe's opportunity, as a more social economic block in a world that has suddenly become a cold, inhospitable, world.
